Scraping Data from Facebook with Python

The right way to do this is to use the facebook API. For various business, security, and privacy reasons they go out of their way to make scraping data tricky.

If you insist on scraping I would try to log in first using mechanize to submit the form. I've never tried to do this with facebook, but alot of websites have easier to parse versions intended for mobile users at m.site.com.

You should look into using facepy by Johannes Gorset. He has done a brilliant job. I used it when I worked on a small Facebook app for a personal project.
