Modules and Packages

Split code into files (modules) and folders (packages), and import what you need.

Beginner

import math
from statistics import mean
import numpy as np

Any .py file is a module; a folder of modules is a package. The code under if __name__ == "__main__": runs only when the file is executed directly, not when imported.
