How do I create a constant in Python?

Question

Is there a way to declare a constant in Python? In Java we can create constant values in this manner:

public static          


        

Answer 1

The Pythonic way of declaring "constants" is basically a module level variable:

RED = 1
GREEN = 2
BLUE = 3

And then write your classes or functions. Since constants are almost always integers, and they are also immutable in Python, you have a very little chance of altering it.

Unless, of course, if you explicitly set RED = 2.
