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.

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.

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.
