So It does not work, cannot read python script. What could be a problem?!? I have saved my python script in the directory where is my workbench.

I think the problem is knowing the path python looks in to find scripts. Within FME this can be confusing. A solutions for you might be to add the path to your script in the code like this:

import sys
sys.path.append("c:\\MyPath\")
import module2.py

You can see the python path (where it is looking for scripts) by adding this to your script

import sys
from pprint import pprint as p
p(sys.path)

For other solutions to dealing with the python path, this is a good article.
