Download a file from a link in Python

I recently got a question and it looked like this : how to download a file from a link in Python?

Python: submit authenticated form using cookie and session

Recently I was challenged to do bulk submits thru an authenticated form, the website requiring a login. While there are plenty of examples of how to use POST and GET in Python, I want to share with you how I’ve done the handling of session along with a cookie and authenticity token (CSRF-like protection).

This crawler is simple, but you can learn many things from this example (especially if you’re new to scraping in Python).
