can a function be static and non-static in python 2

Question

Lets say I have this class:

class Test(object):
    def __init__(self, a):
        self.a = a

    def test(self, b):
        if isinstance(self, Test):
                 


        

Answer 1

If you want something that will actually receive self if called on an instance, but can also be called on the class, writing your own descriptor type may be advisable:

import types

class ClassOrInstanceMethod(object):
    def __init__(self, wrapped):
        self.wrapped = wrapped
    def __get__(self, instance, owner):
        if instance is None:
            instance = owner
        return self.wrapped.__get__(instance, owner)

class demo(object):
    @ClassOrInstanceMethod
    def foo(self):
        # self will be the class if this is called on the class
        print(self)

Demo.

For the original version of your question, you could just write it like any other static method, with @staticmethod. Calling a static method on an instance works the same as calling it on the class:

class Test(object):
    @staticmethod
    def test(a, b):
        return a + b

Demo.
