First, Module introduction

Module, a collection of code that implements a function with a single piece of code.

Like functional programming and process-oriented programming, functional programming accomplishes a function, and other code is used to invoke it, providing reusability of code and coupling between the code. For a complex function, Ken needs multiple functions to complete (functions can be in different. py files), and the Code collection consisting of N. py files is called a module.

such as: OS is a system-related module; file is a module related to the operation of files.

The modules are divided into three types:

• Custom Modules
• Built-in standard module (also known as standard library)
• Open source Module
