Importing modules

Slide 1 / 5

A module is a file of Python code ā€” variables and functions ā€” that you load with import.

import math math.pi ā†’ 3.141592653589793 math.log(32, 2) ā†’ 5.0 math.sqrt(16) ā†’ 4.0

Everything in the module is reached with a dot. The standard library ā€” math, random, datetime, json, and hundreds more ā€” comes with Python, no install needed.
