Module clarification

[Hussein B]

Hi.
I'm a Java guy and I'm playing around Python these days...
In Java, we organize our classes into packages and then jarring the
packages into JAR files.
What are modules in Python?
What is the equivalent of modules in Java?
Please correct me if I'm wrong:
I saved my Python code under the file   Wow.py
Wow.py is now a module and I can use it in other Python code:
import Wow

Thanks.
