Python has no way to enforce a variable to be a constant.

The nearest you can go is to use an enum:

class Constants(Enum):
    WIDTH = 1024
    HEIGHT = 256

And get to each value using for example Constants.WIDTH.value.

No one can reassign that value.

Otherwise if you want to rely on naming conventions, you can adhere to this one: declare variables that should never change uppercase:

WIDTH = 1024

No one will prevent to overwrite this value, and Python will not stop it.

That’s what does most Python code you will see.

The 2021 JavaScript Full-Stack Bootcamp will start at the end of March 2021. Don't miss this opportunity, signup to the waiting list!
