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)

import types

class ClassMethod(object):

    def __init__(self, func):
        self.func = func

    def __get__(self, obj, objtype=None):
        return types.MethodType(self.func, objtype or type(obj), type)

def class_method(func):
    return ClassMethod(func)

why staticmethod need tow params "obj" and "cls"??It seems useless

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