You might be wondering what a Python “package” is, and how it relates to the Python module. Essentially, a package is a group of modules with an __init__.py fie that ties them all together.

After the initial comments I added two import statements to gain access to the Python random and math modules. The demo program consists mostly of a program-defined NeuralNetwork class.

Devs unknowingly use “malicious” modules snuck into official Python repository Code packages available in PyPI contained modified installation scripts.
