pure Python implementation of the staticmethod decorator

staticmethod.py

class StaticMethod(object):
    def __init__(self, func):
        self.func = func


    def __get__(self, obj, cls):
        return self.func


def staticmethod(func):
    return StaticMethod(func)

@dogewzy, it's Python descriptors protocol, pls see details in https://docs.python.org/3.7/reference/datamodel.html#object.__get__
