Python Learning (10)--Modules and packages

First, the module

A module is a file that contains the Python definition and reputation, and the filename is the module name plus the. py suffix.

Import loaded modules are divided into four general categories:

1. Code written using Python (. py file)

2. C or C + + extensions that have been compiled as shared libraries or DLLs

3. Package a set of modules

4. Built-in modules written and linked to the Python interpreter using C
