I am looking for some real help. I want to web scraping using Python, I need it because i want to import some database, How can we do that in Python. What libraries do we need ?
You can use 
1) Beautiful Soup
2) Python Requests
3) Scrapy
4) Mechanize
... and many more. These are the most popular tools, and easy to learn for the beginner. 
From there, you can branch out to more complex stuff such as UserAgentSpoofing, HTML Load balancing, Regex, XPATH and CSS Selectors. You will need these to scrape more difficult sites that has protection or login fields. 
Hope that helps. 
Cheers
