extract.py throws SyntaxError

[Markcanfly]

When trying to run extract.py I get this error:
$ python extract.py File "extract.py", line 12 files = [x for x in files if not ".py" in x] ^ SyntaxError: invalid syntax

sorry, I noticed the problem a couple of days ago and fixed it but forgot to push to master.

should be fixed in the latest commit

also, try using the new branch, it might have fewer errors
