The @classmethod decorator is a built-in function decorator which is an expression that gets evaluated after your function is defined. The result of that evaluation shadows your function definition. A class method receives the class as the implicit first argument, just like an instance method receives the instance.Since Python 3.8, the typing module includes a Final class that allows you to type-annotate constants. If you use this class when defining your constants, then you’ll tell static type checkers like mypy that your constants shouldn’t be reassigned. This way, the type checker can help you detect unauthorized assignments on your constants.class unittest.TextTestRunner(stream=None, descriptions=True, verbosity=1, failfast=False, buffer=False, resultclass=None, warnings=None, *, tb_locals=False, durations=None) ¶.
