Suggested January 2024 How To Find Beautifulsoup By Class?

Introduction to BeautifulSoup Find

BeautifulSoup find is a python package for parsing HTML and XML files and extracting data. An XML passed to a BeautifulSoup function Object. BeautifulSoup has parsed the document and produces data structure in memory corresponding to it. Find and find all are the most commonly used methods for locating anything on a webpage. BeautifulSoup find is handy and important in python.

What is BeautifulSoup Find?

When we feed BeautifulSoup a well-formed document, the processed data structure looks exactly like the original. This is because beautifulSoup find employs heuristics to develop a viable data structure.

BeautifulSoup uses a class named UnicodeDammit to receive and convert them to Unicode regardless of the encoding. We can use UnicodeDammit by itself if we need to perform documents of others (without needing BeautifulSoup to parse them). The Universal Feed Parser’s code largely influences it.

BeautifulSoup is a widely used Python package for navigating, searching and extracting data from HTML or XML webpages.

How to find BeautifulSoup by Class?

The find method returns an object of type bs4 after locating the first tag with the supplied id or name. BeautifulSoup has a lot of ways for searching through a parse tree. Find and find all are two of the most commonly used techniques.

We have a variety of filters that we are passing into this method, and it’s essential to understand them because they’re used often throughout the search API. These filters can be applied to tags based on their names, attributes, string text, or combination.

A string is one of the most basic types of filter. BeautifulSoup will do a match on a string if we pass it to the search method. We can search for all tags that begin with a specific string or tag.

The below steps show how to find BeautifulSoup by class as follows.

In this step, we are installing the bs4 package by using the pip command. Bs4 box is used to import all the BeautifulSoup modules.

pip install bs4

After installing the bs4 package in this step, we create the HTML page. We have made the below HTML page to find BeautifulSoup by class as follows.

Code:

After creating the HTML code in this step, we open the python shell using the python3 command.

python3

After opening the python shell, we import the BeautifulSoup, os, and requests modules. We are importing the BeautifulSoup module using the bs4 package as follows.

from bs4 import BeautifulSoup import os, requests

To use BeautifulSoup find, we need to import the module of bs4; without importing the bs4 module, we cannot use the BeautifulSoup module in our code.

After importing the BeautifulSoup, os, and requests modules in this step, we check how to find BeautifulSoup by class.

Code:

from bs4 import BeautifulSoup import os, requests py_con = chúng tôi (url) py_soup = BeautifulSoup (py_con.text, 'html.parser') print (py_soup.find ('title'))

In the above example, we can see that first, we have imported the bs4, os, and requests modules. Then, after importing the module, we use the HTML page URL we created.

After using the URL, we accessed this URL using the requests and get method. After accessing the URL, we use BeautifulSoup by using the html.parser. Then we print the title of the HTML web page by using the BeautifulSoup find method.

BeautifulSoup Find all class

BeautifulSoup (bs4) is a Python module that extracts information from HTML files. This module is not included with python. We are executing the “pip install bs4” command in the terminal to install it.

Queries make it very simple to send HTTP/1.1 requests. Unfortunately, the request module is also not included with python. We are executing the “pip install request” command in the terminal to install it.

The below example shows find all classes by URL are as follows.

from bs4 import BeautifulSoup import requests py_con = chúng tôi (url) py_soup = BeautifulSoup (py_con.text, 'html.parser') print (py_soup.find_all ('title'))

In the above example, we can see that we have imported the bs4 and requests module. Then we are using the HTML page URL.

After using the URL, we have access to the URL by using the requests and get method. Then we are using BeautifulSoup by using the html.parser.

To print the data from the HTML web page, we are using the find_all method.

BeautifulSoup Find Searching

The find method is discovered on the page, and the find function returns the result. It’s only used to get the first tag of an incoming HTML object that meets the requirement.

As a result, we can only print the first search. After scanning the entire document, find all is used to return all matches.

We created the HTML document in the example below when writing the BeautifulSoup code.

The below example shows searching the class using a given HTML document.

Code:

“”” from bs4 import BeautifulSoup py_soup = BeautifulSoup ( py_html , ‘html.parser’) py_soup.find ( class_ = “body” )

Conclusion

BeautifulSoup is a widely used Python package for navigating, searching and extracting data from HTML or XML webpages. BeautifulSoup find is a python package for parsing HTML and XML files and extracting data. The find method returns the object of type bs4 after locating the first tag with the supplied id or name.

Best Iphone Apps To Find A Song By Humming (2023)

While there are a few song recognizer apps for iPhones out there, very few apps can recognize a song if the user is humming it. Thankfully, with the magic of technology and AI, you can now find out the name of the song that’s been stuck in your head for hours on end!

In fact, the way that AI works is quite ingenious. It takes your humming waveform for the elusive song (small snippets only) and compares it to similar waveforms on the database. Of course, it doesn’t have to be completely on point, but it helps if you are audible and clear when you’re humming the song. So, I’ve listed the iPhone apps that will help you recognize a song by humming its tune or lyrics.

1. Apple’s Siri – Editor’s choice

When it comes to apps that recognize songs, especially for Apple products, very few will be as compatible and accurate as Siri. Apple has done a magnificent job on its end with the programming for its resident AI assistant, ensuring that Siri can help you in pretty much every way possible.

However, there’s a small catch. Siri itself isn’t responsible for recognizing the song that you’re humming. When you tap on your phone’s Home button and ask Siri to recognize the song, it’ll often use a third-party app called Shazam. The reason for this is that Shazam has one of the largest databases of sound waveforms in the world.

Shazam was one of the companies Apple acquired for roughly $400 million in 2023. Siri now uses this app for recognizing songs. Even though Siri isn’t directly identifying a song for you, it’s good to know that Apple has ensured this service with all of its products.

Pros

Decent database thanks to Shazam integration

Doesn’t need the Shazam app to be used

Quite fast in recognizing songs

Cons

Have to be very audible and clear when humming

Price: Free

2. Shazam – Vast database

If Siri using Shazam isn’t your cup of coffee, you could always download the Shazam app directly onto your iPhone. This is one of the best apps to identify songs by humming and also to keep track of your song recognition history.

Using the app is pretty easy too. When you’re humming a song or having a song played in the background, just open the app and tap on the icon in the middle of the screen. In a few seconds, you should have the name of the app at your fingertips!

After the song has been identified, you’ll also be provided with links to the song on Spotify, YouTube, and iTunes. However, the only issue with the app at the moment is that it needs to expand its Asian music database.

Pros

Vast database for music identification

Extremely convenient to use

Provides song links through Spotify, YouTube, Apple Music

Cons

Needs to add more Asian music to the database

Price: Free

Download

3. SoundHound – Integrates with Apple Watch

If there is any app that gives Shazam stiff competition, it’s SoundHound. The app was first developed in 2005 and since then has become one of the biggest music discovery apps in the world. You’ll find plenty of music aficionados debating on which app is better – Soundhound or Shazam!

However, one area where SoundHound stands out is the Apple Watch integration. The Apple Watch version of the app can help you identify music quicker and also provides LiveLyrics.

Apart from this, the app provides complete Apple Music and Spotify integration as well. You’ll be able to explore across genres and diversify your music taste with immaculate ease. In case you don’t have Apple Music or Spotify subscriptions, SoundHound also has a free built-in YouTube player that you can use to listen to newly identified music.

You can also save all your recently searched tracks for easier picking later on. Moreover, as an enthusiast listener, the artists/songs also have their biographies provided on the app. Overall, SoundHound provides a holistic listening and music discovery experience.

Pros

Integrates with Apple Watch

Built-in YouTube player for music videos

Artists, songs, and albums have biographies for more information

Cons

Most of the features are only available through the Premium subscription

Price: Free (In-app purchases start at $6.99)

Download

4. Google app – Decent free option

If you’re looking for a free app that identifies songs, you don’t really have to look much further than the Google App on your phone. On October 15, 2023, Google added an update to its database that allowed Google Assistant to identify songs. Of course, it’s been a while since then, and most updated smartphones have this feature through Google.

To use the app and this “searching by humming” feature, you’ll have to open the Google app. After opening the app, you’ll find the Mic button in the middle of the screen. Tap on this and then select the “Search a song” option at the bottom of the box. After this, hum your favorite tune or play a song. The app will ‘listen’ to the waveforms and run a comparative analysis. After this, it should provide you with an accurate answer.

While it’s nice to see that Google has added this feature to the Search bar, the database will need constant updates. The results of this Search or Listen feature aren’t always accurate. In fact, the accuracy is far lower than that of other music identification or music discovery apps. Considering this, I’d recommend the app as an experiment or as a backup option!

Pros

Very easy to use

Available on every recent iPhone

Cons

The accuracy for identifying songs needs to be better

Its database needs to be updated with more songs

Price: Free

Find Angle While Angle By Similar Chord At Center In Java

A circle is a round shape two-dimensional diagram that has no corners. Every circle has an origin point and every point on the circle maintains an equal distance from the origin. The distance between the origin and a point in a circle is known as the Radius of the circle. And similarly, if we draw a line from one edge to another edge of the circle and the origin is held in the middle of it, that line is known as the diameter of the circle. Basically, the diameter is double of the length of the radius.

The chord of the circle refers to a line touching from one endpoint of the circle to another endpoint of the circle. Or simply we can say a chord refers to the line whose endpoints lie on the circle. A chord divides the circle into two parts.

As per the problem statement, we have to find the length of the chord when the radius of the circle and angle subtended at the center by the chord is given.

Logic to find length of chord −

Angle subtended by the chord at centre = Angle subtended by another chord of same length at centre

So, let’s explore.

To Show You Some Instances Instance-1

Let say angle subtended by the chord at centre = 60

So, the angle subtended by another chord of same length at centre = 60

Instance-2

Let say angle subtended by the chord at centre = 45

So, the angle subtended by another chord of same length at centre = 45

Instance-3

Let say angle subtended by the chord at centre = 52

So, the angle subtended by another chord of same length at centre = 52

Algorithm

Step 1 − Get the angle at the centre subtended by the chord either by static input or by user input.

Step 2 − Find the angle at the centre subtended by another chord of same length by using the above explained logic.

Step 3 − Print the result.

Multiple Approaches

We have provided the solution in different approaches.

By Using Static Input Value

By Using User-Defined Method

By Using User Input Value

Let’s see the program along with its output one by one.

Approach-1: By Using Static Input Value Example

In this approach, we initialize the angle subtended by the chord in the program. Then by using the algorithm we can find angle subtended by another chord.

import java.io.*; public class Main{ public static void main (String[] args){ int angle = 52; System.out.println("Angle subtended at the center by the chord: "+angle+" degrees"); } } Output Angle subtended at the center by the chord: 52 degrees Approach-2: By Using User Defined Method Example

In this approach, we take user input of the angle subtended by the chord. Then call a user defined method by passing this value as parameter and inside the method by using the algorithm we can find the angle subtended by another chord.

import java.io.*; public class Main{ public static void main (String[] args){ int angle = 40; findAngle(angle); } static void findAngle(int angle){ System.out.println("Angle subtended at the centre by the chord: "+angle+" degrees"); } } Output Angle subtended at the centre by the chord: 40 degrees Approach-3: By Using User Input Value Example

In this approach, we take the user input of the angle subtended by the chord in the program. Then by using the algorithm we can find angle subtended by another chord.

import java.io.*; import java.util.*; public class Main{ public static void main (String[] args){ Scanner sc = new Scanner(System.in); System.out.println("Enter the angle subtended at center by the chord:"); int angle = sc.nextInt(); System.out.println("Angle subtended at the center by the chord: "+angle+" degrees"); } } Output Enter the angle subtended at center by the chord: 55 Angle subtended at the center by the chord: 55 degrees

In this article, we explored how to find the angle subtended by a chord when the angle subtended by another chord of the same length is given by using different approaches in Java.

How To Find The Sas Length?

Introduction to SAS Length

SAS length is the kind of operation and it is mainly used as the 8 bytes characters for storing the numeric set of values in the variables that may contain the integer values also it does store as the less than 8 bytes characters the data sets containing many integer variables and indicate the variables for reducing the sizes by more than 50% of the datasets.

Start Your Free Data Science Course

What is SAS length?

The SAS length is the number of variables that allocates the memory for storing the data values in the variables and does not necessarily use the same number of characters in the single variables. It can be used to reduce the size and disk space of the SAS data sets that are stored as 8 bytes characters for storing a numeric set of values in the variables and the integer values. It may also accept less than 8 bytes characters in the length function to perform the operations in the datasets. The datasets contain many integer variables that collected the data questionnaire and indicate the variables for reducing the size by more than 50% of the allocated spaces. The variables contain a real set of numbers that should be in the left position with a default length is 8.

How to Find the SAS Length?

The length of the variables helps to determine the large extent data size of the datasets. If the data length is set correctly that might reduce the data size of the dataset by 50%. In SAS the length is one of the functions that help to return the length of the non-blank characters which include the string and exclude the leading and trailing blanks. Length function has the obligatory set of parameters and arguments which as the string name characters that can be the variable, a constant, or any expression. As we mentioned the length function helps to determine and find the number of characters in the SAS variable with created datasets along with one variable for set the value in column characters. The column length in SAS terms to store the amount of datas allocation in the dataset to hold the column values which is to specify the byte’s length for specifying a numeric set of columns on the valid length which is usually set through 3 or 8. Whenever the length of the datas is specified through the data precision which allocated the column values. The length function always returns the value for less than or equal to the values returned by the lengthc keyword. The function will return the integer value which mainly represented the position of the characters that may be the last set of strings and trailing blanks will be ignored and it points to the two sets of points on the function. First, if the function is the set numeric set of constants or variables the SAS will be converted to the right justified string characters by using BEST12 formats.

In the second set of points is to be noted that the character string is returned at the missing set of expected values. We can use the find function to search the position of the strings like substrings within the new data.

Steps to create and find the SAS character length

Navigate to below URL,

By using the following code the length is calculated,

data first;

informat name dept $10. id 3.4;

input name dept id deptid;

length name $10 default=3;

datalines;

Sivaraman IT 1 12

;

proc contents data=first;

run;

proc print data=first;

run;

16. We can get the output results as below,

SAS Length statement

The SAS length statement and it’s a function to return the character length of the string and it’s specified with the byte format. Storing as the character and numeric set of variables or any number of characters for storing and accessing the varchar variables. The length of the variable depends upon the data information whether the variable is numeric or character and how the variable was created. Whether the LENGTH of the statement or ATTRIB statement is presented at the SAS session which encodes the program code for data processing.

It also followed the subject rules for assigning the lengths, character, and numeric set of lengths which are assigned as the VARCHAR variables for allocating the memory for each type. User session is encoding and declaring the variable type for single-byte with a minimum of 100 bytes. It accepted the UTF-8 encoding and SAS session for the character can take upto 4 bytes to 400 bytes might be used by each variable which is assigned the types as VARCHAR(100) or another type with the same length. A comma, blank space, and other special characters are accepted for declaring and performing the user operations.

data first;

inp1 = length(“Welcome”);

put “The number of given input characters in ‘Welcome’ is: ” inp1;

inp2 = length(“To123%&$”);

put “The number of given input characters in ‘To123%&$’ is: ” inp2;

run;

In the above example, we used length() function of the given input strings. We can create the variable and pass the input strings in the length() function.

2. And used the put keyword to count the character’s length and assign it to the specific variable like inp1.

3. The same process is applicable for the inp2, here additionally we can pass the numbers, special characters, symbols, etc.

Special characters are calculated and processed in the datas in the backend which is similar to the normal string characters inputs.

By using the put keyword the results are assigned to the inp2 variable.

Conclusion

The SAS length is the function, statement, and keyword for declaring and fetching the data counts on the given SAS program code. It has a lot of default keywords and functions it’s the basic way to calculate the data counts of the parameters as well as the user inputs.

Examples On How Does Class Work In Perl

Definition of Perl Class

Web development, programming languages, Software testing & others

How to Declare Perl Class?

The procedure is as follows.

It is very easy and simple to declare. To declare any class we need to mention package keyword before the class name.

Syntax:

Package class_name;

Parameter:

Below is a parameter description of Perl declare syntax.

Package: Package is nothing but a specified namespace within the Perl code or program which contains sub-routines or user-defined variables. The package is very important at the time of declaring the class.

Class name: We can define any class name to the program in Perl. But it is specific to the program which we have implemented.

A package name in perl class is subroutines or a user-defined variable. We can reuse this again in the code.

Package in perl will provide namespace within the program mostly which contains subroutines and variables.

The scope of class or package will end of the file or until we cannot create another package in one file.

Below is the example to declare per class is as follows.

Example:

Package declare_perlClass;

In the above example, we have declared class name as declare_perlClass. This class corresponds to a package name.

Before declaring declare_perlClass class firstly we need to load the package in Perl.

A loaded package is used in throughout the program. The scope of the package is throughout the program or until we define another package.

How does Class Work in Perl?

The working is as follows:

It is defined as it is a package that having constructor to create perl object, this object is having any type of variable but mostly it is a reference to array or hash is used.

It is nothing but a concept of data structures. It defines the object of data in perl.

To define we need to build a package first, the package is nothing but sub-routines or user-defined variables.

The object is nothing but an instance of the class.

It is very easy and simple to define, Itl is corresponding to a package of perl in its simplest form.

It is most important and useful in Perl to define Perl’s object.

We have to take the example of class as an employee. We have defining member function and data members using the class as an employee.

There may be an employee with different names and structures but all of them have some common characteristics like emp_id, emp_dept, and emp_name.

Here we have to define an employee as a class with emp_id, emp_dept, and emp_name as data members.

We have also used a bless function.

Syntax bless function:

bless name_of_object, name_of_class;

We can also create an object by using a perl class. We have to create an object based on the class name.

Data member in perl class is nothing but data variables and member function is a function which manipulated the variables.

In the below example, we have to define member variable as emp_id, emp_dept and emp_name.

We can define any class name to the program in perl. But it is specific to the program which we have implemented.

In the above example we have to define class name as employee and data member as emp_id, emp_dept and emp_name.

Examples

The examples are as follows:

Example #1 – Using bless function in perl class:

In the below example, we have created perl class using bless function. We have created a class name as an employee.

Member variables of class name is ’emp_id’ and ’emp_salary’.

We have defined a bless function. In bless function, we have to define object name and class name.

We have also define constructor of employee class name as new_emp to define member variables.

Code:

use strict; use warnings; package employee; ## Constructor of employee class. sub new_emp{ #the package name 'employee' is in the default array shift. my $class = shift; #object of a class. my $self = { }; #blessing with object name and class name bless $self, $class; #returning object from constructor return $self; } 1; print "emp_id:- 101n"; print "emp_salary:- 25000n";

Example #2 – creating class and using objects

In the below example we have created perl class using an object. We have created class name as an employee.

Member variables of class name is ‘Employee_FirstName’ and ‘Employee_LastName’.

We have defined a bless function. In bless function, we have to define object name and class name.

We have also define constructor of employee class name as employee_data to define member variables.

Code:

use strict; use warnings; package employee; ## This is the class of employee. sub employee_data ## Constructor of employee class. { # Shift is default array will used in 'employee' class and then assign # it to employee class variables my $class_name = shift; my $self = { }; # using bless function. bless $self, $class_name; # returning object from constructor of employee_data. return $self; } # Object creating name as employee from employee_data and calling a constructor. my $Data = employee_data employee("Emp_FirstName:- ABC", "Emp_LastName:- PQR"); # printing the data

How To Find An Instagram Email Address

Are you looking to find an Instagram email address?

Maybe you want to contact an influencer or a creator.

Or maybe you want to promote your product or service.

Either way, you can either send a direct message to the person or send them an email.

Instagram has a feature where you can add your email address and display it on your profile.

If you do this, others will be able to email you.

However, not many people have enabled it, so you’ll need to find other ways to contact them.

In this guide, you’ll learn how to find your or someone else’s Instagram email address.

How to find an Instagram email address

To find an Instagram email address, you need to look for an “Email” button on the person’s profile.

If their profile does not have an “Email” button, you need to Google the person to find their email address.

Alternatively, you can send them a direct message by tapping on “Message”.

If the person’s Instagram profile is set to private, tap on the three dots followed by “Send Message” to send them a message.

Some Instagram users have their personal blog or website in their bio.

If so, you need to visit the link(s) and check if there’s an email address.

You can also try finding the person’s LinkedIn profile on Google.

Some people will add their email address to their LinkedIn profile via “Contact info”.

Here are two ways to find an Instagram email address:

Method 1: Tap on “Email”

To find someone’s Instagram email address, you need to look for an “Email” button.

The “Email” button will be located next to the “Message” button.

However, it’ll only appear if the person added it to their profile.

After you’ve tapped on the “Email” button, you’ll see the person’s email address.

Instagram has a feature where you can add your contact information to your profile.

To do this, you need to have a business account.

Lastly, edit your profile again, tap on “Profile display”, and enable “Display contact info”.

As adding an “Email” button is difficult, not many people have done it.

If the person does not have an “Email” button on their profile, you need to check if they included their personal website in their bio.

If they did, visit their website and try finding their contact information there.

Method 2: Google the person

The second method is to Google the person and try to find their email address from one or more of the search results.

The first technique that you should try is using quotation marks.

Putting a word or a phrase inside quotation marks will tell Google to search for an exact match of it.

An example of what you should search for is “full name” + contact.

For example, if you want to find Gary Vee’s email address, search for “Gary Vee” + contact on Google.

If the person has a personal website with their contact information, it will be shown on the search results.

Another way is to search for the person’s LinkedIn profile.

To do so, search for “Gary Vee” + LinkedIn on Google.

Some people include their email addresses on their LinkedIn profiles.

How to find your Instagram email address

Open the Instagram app.

Tap on your profile picture on the bottom navigation bar to go to your Instagram profile.

Tap on the menu icon on the top navigation bar.

Select “Settings”.

Select “Account”.

Tap on “Personal information”.

After you’ve tapped on “Personal information”, you’ll be able to see your personal information.

This includes your email address, phone number, gender, and date of birth.

Your personal information will not be part of your public profile.

If you want to add your email address to your profile, you need to do it manually.

Conclusion

Finding someone’s Instagram email can be challenging especially if they didn’t add an “Email” button on their profile.

If you can’t find it, you can send a direct message instead.

To do so, visit the person’s Instagram profile and tap on “Message”.

If it’s a private account, tap on the three dots followed by “Message”.

You can also try sending a message or tagging the person on Twitter to get their attention.
