How do beginners learn Web Scraping with Beautiful Soup in Python?

A beginner, when learning about Python or any programming language, should focus on how to use a programming language for solving problem. One of the most widely used data-mining and data-processing software in the world is Python, and this article tells you how to use python to retrieve data from websites.

What is Beautiful Soup? If you are reading this tutorial, you may think it is an advanced skill or know-how. It isn't a complex code language like Java or Ruby. But it is actually quite simple to make and process web pages in a few lines of python code. So, it has no rocket science and it is easier to get started with web scraping rather than learning a whole new software like Java or python.

Beautiful Soup 4 is included in the standard library for python. So, the main concept here is that it does the job in an easy and quick way which is much faster than what we normally have to do using raw codes. In Python, it takes one line of code to do all the tasks done by 5-7 lines of codes previously.

To know how to use beautifulsoup, one must have knowledge of HTML/CSS/JavaScript (or at least understand it). That's all. Let's look into how to scrape data using beautifulsoup.

How does it work? We must first understand the basics of HTML/CSS/JavaScript language that we encounter while browsing the Internet. While surfing through the sites, we notice the tags used. These tag elements can be used to make hyperlinks, images, forms, etc. When we hit the links, images, forms, then the page displays the corresponding tag element along with other information associated with it. It may also contain other elements as well. To fetch the information you have to write a code (Python) that can detect and locate these tag elements within the website. When the code gets a tag element, it parses the data in it as text in your code. But this element might come as a form field, so if you want to parse the data that goes in that particular field, you need a different approach. The first method is using regular expressions, the second one is using Selenium. For a beginner, this would be enough to learn.

What are the prerequisites to learn Web Scraping with Beautiful Soup in Python?

The world is moving at a faster pace today and the Web is playing a big role in it. The Internet has become the most prominent platform where consumers search, compare and purchase items. Today, one should need to be fluent in both the computer language and the programming language to get ahead in his career and take the competition further.

In this article, we will help you understand the Python programming language and also web scraping using BeautifulSoup. We will begin with the basic concepts of Python, learn the basics of BeautifulSoup, then go on to build a crawler that scrapes information from a website in one single run. We will take the example of Amazon.com to demonstrate the process of web scraping and learn about data extraction with Python.

What is Python? Python is a widely used object-oriented programming language. Created by Guido Van Rossum, the language became popular because of its readability, comprehensibility and ease of use. It is a dynamic programming language which enables developers to write robust software and to write very complex programs.

Since its first release in 1991, Python has been developing its features, which are now available to the public. Python is fast, powerful and stable; it is an open source language and can run in multiple operating systems like Mac, Linux, Windows.

Python is a highly versatile language with the ability to develop a wide range of applications. The language can create interactive applications and scripts in the terminal as well as graphical apps in Tkinter. It is the language which can be used by beginners as well as professionals.

BeautifulSoup - Introduction. Beautiful Soup is a simple library for parsing HTML or XML documents in Python. It is also a tool for web scraping. It can handle HTML documents and HTML and XML tags easily, unlike other libraries.

Soup parses HTML files and then turns them into Python objects. You can even create beautiful documents without knowing HTML.

Soup is used to turn web pages into an actual document. By default, the library gives the user all the information necessary to do this job. However, you can customize the output and can decide what to do with the results.

It is a really easy and powerful library for parsing and extracting information. It is especially good for extracting data from the web page, making it easy for you to process the data on the server side.
