Stab in the dark here:

Are you perhaps importing your original script as a module someplace?  
If you have recursive imports, you can actually see two instances of the 
same module, which can lead to the kind of behavior you're describing.

If your main script is called   main.py,  then search for any reference 
to main in another source file, in a line such as

import main
or
from main import fh

or some such.
