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
