Table of Contents

Consider a situation where you have to pull a massive amount of data, and you want to do it as soon as possible.  It’s not possible to do it manually without going to each website and looking for data. Here web scraping is your solution. With web scraping, you can complete your work easier and faster.  Web scraping is a process where raw data is collected and parsed. The python community has now come with several web scraping tools to ease your work. There is a huge amount of data available on the internet. There is some information and misinformation available all over the internet. There are several regulations such as data science, investigating business and business intelligence, etc. 

In order to effectively use this data, you need to be an expert in web scraping. With web scraping in Python, you can efficiently collect relevant data types. They provide you with tools to get the task quickly done. In this blog, you will learn to extract data, manipulate and use clean data, and data visualization with the help of the python library.  Web scraping is used to define the use of algorithms for extracting vast amounts of data. The capability to scrape data from the web is a must-have skill in the current times. 

Is Web Scraping Legal?


When it comes to the legality of scraping, not every website allows web scraping. Thus we cannot say web scraping is entirely legal. Web scraping is similar to any other tool available. You can either use scrapping for good or bad things. We cannot conclude here that web scraping is illegal. Web scraping is entirely associated with search engines like bing or google. Search engines scrap the website and indexes. These search engines build trust and bring traffic back to your website. These are experts in creating a favorable view towards web scraping. 

The legality of scraping here depends on what you do with the acquired data. Web scraping can be considered illegal if the data you are manipulating is non-public. Non-public data is something that is not created for everyone’s reach on the browser. You need to log in to get access to this data. Here web scraping is unethical. 


What Is Web Scraping, And Why Is This Used For?


Web scraping is a technique that extracts data in large quantities from different websites. Scrapping refers to obtaining information from other web sources, providing information from other sources, and saving it as a local file.  They collect automated unstructured data and convert them into amorphous forms. The different ways of scraping webs are to provide online services, APS, or writing of codes.  There are some free Bootcamp coding available in the market by which you can also gain more knowledge about web scraping. If you are web scraping your page for educational purposes, then you can not have any problem. While web scraping, it is essential to take time and look for terms and conditions to ensure violation before starting a large-scale project. 

Here are some uses of web scraping:

  • Services such as parsehub use web scraping for price comparison. 
  • Web Scraping is used to collect email ids in bulk for email marketing purposes. 
  • Web scraping is very helpful in collecting data from different social media platforms to find out what is trending.
  • The data collection from web scraping can be used to analyze and conduct surveys for research and development.
  • Different data regarding job interviews and vacancies can be collected with the help of web scraping. The user here can get easy access to the data at one point. 
  • It’s beneficial in creating genuine news for your business. It helps in monitoring and parsing critical stories that directly influence the stock market. 


 Why Is Python Good For Web Scraping?


Just like PHP, Python is also one of the ideal languages for web scraping. Python is a complete programming language that is capable of handling every data extraction properly. Scrappy, beauty soap, and requests are the three majorly used python frameworks. Beauty soap alone is capable of processing lots of ease into your works. They have a robust library that is efficient in high-speed scraping tasks. 

Python is a highly interpreted language in general programming used for scraping data quickly. They are effective in web scraping and allow automatic memory management that eases your work. The most distinctive feature of web scraping is the efficient library and framework, which is easy to learn.  It provides server-side programming script language designs for web development and web scraping. It’s beneficial in targeting dynamic and simple web pages. 

Key features of Python for web scraping are:

  • They have a comprehensive framework that eases up your tasks of web scraping. 
  • Its effectively developed beautiful soap is efficient at data extraction
  • The pythonic idioms and navigation are used for searching and modifying the valid parse
  • The efficient web scraping library makes it an efficient tool.


How Do You Scrape Data From A Website?


There are many programming languages used for web scraping. But the reason behind using Python for web scraping is its efficiency in data extraction. 

The data extraction is done in two parts, web scraping and web crawler. In simple words, web crawlers are essential for web scraping for the extraction of required data. Here are the main components of scraping data from a website:

  • Crawler: crawlers are generally considered spiders. It’s an artificial technology that uses the internet for index searches from the links of given contents. It searches for relevant information about the programmer. 
  • Scrapper: it’s a tool designed to extract data from several websites. These are widely used designs with complexities depending upon different projects. 

Understanding the concept of web scraping for data extraction: 

  • Look for the URL: understanding the requirements of your data as per your projects. A web page contains a large amount of information.   
  • Inspecting pages: the format of data extraction must be carefully parsed from making noise from raw data. 
  • Writing relevant information and code to run the program.
  • Store the data in the files such as CSV, XML, etc., file format. 


Is Python Best For Data Scraping?


We are surrounded by programming languages all around. Collection and extraction of data are essential skills in the present times. Python offers several libraries which can be used for web scraping. 

Beautiful soap, scrapper, request, urllib, and selenium are some of the libraries provided by Python. Here are overviews for each library in data scraping from Python: 

  • Requests: they are the most straightforward libraries to be used in HTTP. They allow the users to send requests and get responses from the HTTP. It also allows the user to request the server to modify or add content. 
  • Scrappy: scrappy is the most popular web scraping library. It’s the most open framework. It’s a complete tool that provides scraps and crawls around the web systematically. They are designed to develop spiders and crawl around their sites. They are also used for automated monitoring and mining for system testing. 
  • urllib: it’s a library that allows the user to open and parse information. It’s inbuilt in the python library. They are a bit complex as compared to requests.
  • Beautiful soap: it’s used for extracting information from HTML and XML files. It can detect page encoding. This is why it provides more accurate information. It’s an elementary and straightforward library. They are the perfect choice for web scraping. 
  • Selenium: it’s an open-source web tool. They were written in java tools to automate tests. It’s a beginner-friendly tool. They do not require any training for a steep learning curve. It’s a very flexible and expandable tool. They are an ideal choice if you want to scrape a few pages within java. 


Web scraping is used for the extraction and processing of large amounts of data from the web. They are more straightforward ways of data extraction from the web. Python is widely used in web scraping as it helps in the easy and quick extraction of data.
