Refactoring my first python code to learn in deep

I'm beginner for python. Here is my first python demo code. I'm going to re factor this code step by step. any help would be very helpful to learn about python.

Code description

Batch program to xcopy from host PC to remote destnation with multi-processing. Kepler, Python-3.x are my environment.

full code :
