How do I use constants in classes in Python?

In Python, you can define constants in a class by using uppercase variable names. For example:

class MyClass:
    CONSTANT_VALUE = 42

Can you give me an example of how to use that constant in a method?

Sure! You can access the constant using the class name. Here's an example:

class MyClass:
    CONSTANT_VALUE = 42

    def print_constant(self):
        print(MyClass.CONSTANT_VALUE)

What if I want to change the constant value later?

It's generally not recommended to change constants, but if you need to, you can simply reassign it. However, it may lead to confusion.

Are there any best practices for using constants in classes?

Yes! Use descriptive names, keep them in uppercase, and avoid changing their values to maintain clarity and consistency.
