I know this isn't "perfect", but what I do often is have a
Constants.py file that has all my constants in a class which has
__setattr__ over ridden to raise an exception. This has two things;
1. Difficult to modify the attributes, at least accidentally
2. Keeps the name-space less poluted by thousands of constants.
Just an idea, I think do this:
constants = Constants()
x = constants.foo
Seems clean (reasonably) to me.
I think I stole this from the timbot.
