Change the line "execfile(fileName)" to "print fileName" and you may 
discover that the problem isn't with execfile but with your code.

Then read about modules and import, and you may discover that there is a 
better way than execfile.


(I wish that eval, exec and execfile were hidden in a module where noobs 
couldn't trip over them and decide they are the answer to every problem. 
Sigh.)

Looking into my crystal ball, I'm guessing that file a.py contains a line 
that says "execfile('a.py')".
