Modules and packages in Python are used to organize and structure code. Modules are individual files containing Python code, while packages are directories containing multiple modules. To use a module or package in your code, you can import it using the
import statement. For example,
import math imports the math module.
You can then use functions, classes, or variables from the module/package by referencing them with the module/package name. Additionally, you can create your own modules and packages to encapsulate and reuse code.
