I am writing a Python script that can take a Facebook URL and locally save an html file of that Facebook page. Based on the answer to this question: Inherent way to save web page source
I tried using urllib2, but the resulting html file is different (missing some parts) compared to the html file that get from manually right clicking on the Facebook page and saving the entire webpage. Do you know why they would be different and what other Python libraries I could use instead of urllib2?
