Python Constants
New Course Coming Soon:
Get Really Good at Git
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.
Are you intimidated by Git? Can’t figure out merge vs
rebase? Are you afraid of screwing up something any time
you have to do something in Git? Do you rely on ChatGPT
or random people’s answer on StackOverflow to fix your
problems? Your coworkers are tired of explaining Git to
you all the time? Git is something we all need to use,
but few of us really master it. I created this course to
improve your Git (and GitHub) knowledge at a radical
level. A course that helps you feel less frustrated with
Git. Launching Summer 2024. Join the waiting list!
