PYTHONPATH only helps Python find the files to import.
Since the error message is pointing at code insiude the imported 
functions then clearly PYTHONPATH is working just fine.


So what is the error?
Simply that python is saying it cannot find the file.
So it is probably in a different folder to the one in which the program 
is running. You need to provide a valid path to the file,

Thats possible. Or it may e worlking to a different definition of 
success to the one you expect! Counting words and letters is quite a 
subjective past-time.

So what is it doing exactly that seems wrong?
What input? What output? What did you expect?
