Web scraping is used to extract huge amount of data from website which then stored into a local file in your computer or in any other database.

Basically web scraping is not legal. If you request too many times then your IP will automatically blocked then you can't access.

In this concept many people get meta tag and html code as well which is considered to be garbage so to rectify that you should use (.text) after the print statement.

For webscraping you need :

Scrapy – The complete framework
Urllib
Python Requests
Selenium
Beautifulsoup
LXML 

You can download these libraries in your any platform.
- conda install NameOfTheLibrary
- pip install NameOfTheLibrary
