Web scraping is used for gathering public information from web pages for further analyses and store, like e-mails, phone numbers, or some specific data e.g. likes, views, etc.

urllib/urllib2 or Requests are python libraries that allow you to send organic HTTP requests, without the need for manual labor.

Also you need tools for parsing an HTML, those are: BeatifulSoup, lxml

Selenium is another Python library for webscraping.

urllib or beautiful soup are great for smaller things especially getting text from non-changing websites (and those libraries do a better job than selenium at the simple stuff) But if you want something a bit more dynamic; meaning maybe you want to click some things or login and Then grab some text from the web page, thats when you might want to use selenium.
