python中类常量的定义

Question

I'm newbie in python and I wonder if I can do something like this for definition of class constant: Tks

class MyClass:

    @classmethod
    @property
    def MY_CONSTANT(cls):
        return 0

Answer 1

No, that won't work.

This is the typical pattern for class constants:

class MyClass:
    MY_CONSTANT = 0

A lot of things in Python (like read-only attributes) are done by convention in Python.
