Python constants file

You can create a constant name file with a constant variable but it is not truly Constant File because there is no strict concept of constant variables like in other languages in Python.

Python constants file example

A simple example code creates constant.py a Python file that contains only constants and then imports them into your main.py.

constant.py

PI = 3.14159
GRAVITY = 9.81
SPEED_OF_LIGHT = 299792458

main.py

import constants

print(constants.PI)  # 3.14159
print(constants.GRAVITY)  # 9.81
print(constants.SPEED_OF_LIGHT)  # 299792458
