Given this:
It%27s%20me%21
Unencode it and turn it into regular text?
Take a look at urllib.unquote and urllib.unquote_plus.  That will address your problem.  Technically though url "encoding" is the process of passing arguments into a url with the & and ? characters (e.g. www.foo.com?x=11&y=12).
How do I url unencode in Python?
