.pyc vs .py checker

gistfile1.txt

"""
Check .pyc files against .py files in a directory and all its descendants to see if any pyc files do not have their accompanying py files.

To get input for this, run the command:

find . -regex .*pyc? > checker.txt

Check if the line ends in pyc. 
If it does, check if there is a line that is the same without the c.  
If not, print the pyc line.
