If I want to scrape a website that requires login with password first, how can I start scraping it with python using beautifulsoup4 library? Below is what I do for websites that do not require login.
from bs4 import BeautifulSoup import urllib2 url = urllib2.urlopen("http://www.python.org") content = url.read() soup = BeautifulSoup(content) How should the code be changed to accommodate login? Assume that the website I want to scrape is a forum that requires login. An example is http://forum.arduino.cc/index.php

Scraping for personal purposes is usually OK, even if it is copyrighted information, as it could fall under the fair use provision of the intellectual property legislation. However, sharing data for which you don't hold the right to share is illegal.
