What’s the difference between a Python module, class, or package? You might be wondering what a Python “package” is, and how it relates to the Python module.

Python modules are typically installed using a package manager called 'pip', which launches a 'setup.py' file that is made available by the developer of the package for installation purposes.

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

But a recently developed package management tool, PDM — short for Python Development Master — lets you install packages to a project using the PEP 582 storage guidelines.
