The concept of modules, packages, and libraries in Python

Module: is the. py file, which defines functions and variables that can be imported when needed

Package: A concept on a module that packages files for ease of administration. The first article in the package directory

Is __init__.py, then some module files and subdirectories, if there are __init__.py in subdirectories

Then it's the package's child bag.

Common Package Structure:

package_a├──__init__.py├──module_a1.py└──module_a2.py

Library: A collection of related functional modules. This is one of the features of Python that has a powerful standard library, third-party libraries, and custom modules

Spit The Trough: These three concepts are actually modules, but is the difference between the individual and the set, forced death obsessive-compulsive disorder ((╯-╰))
