That's doing it the hard way. Try

   import os.path

and use

   os.path.exists("your suspected file here")

if that doesn't return 0, use

   os.path.isfile("your suspected file here")

or
   
   os.path.isdir("your suspected file here")

To find out if it's a file or a directory. If you do *any* path 
manipulations you'll do yourself a favour by reading the docs on the 
os.path module.
