Introduction to modules and packages
Modules in Python are Python files with a .py extension. In reality, they are a way to organize functions, classes, and variables using one or more Python files such that they are easy to manage, reuse across the different modules, and extend as the programs become complex.
A Python package is the next level of modular programming. A package is like a folder for organizing multiple modules or sub-packages, which is fundamental for sharing the modules for reusability.
Python source files that use only the standard libraries are easy to share and easy to distribute using email, GitHub, and shared drives, with the only caveat being that there should be Python version compatibility. But this sharing approach will not scale for projects that have a decent number of files and have dependencies on third-party libraries and may be developed for a specific version of Python. To rescue the situation, building and sharing packages is a must for efficient...
