Take a look at decompyle (http://www.goebel-consult.de/decompyle/)

To restore a missing myfile.py from the myfile.pyc bytecode you can
do:

>>>import decompyle
>>>outputfile = open('myfile.py','w')
>>>decompyle.decompyle_file('myfile.pyc',outputfile)

This should restore the code nearly identical to the source, though
you will lose any comments and the exact layout of your code, since
these won't be preserved in the .pyc file.

Brian.
