If you read the original post -- I think in this case the details do matter. What is your highlevel explanation for >> class Foo: ... @staticmethod ... def foo(): pass ... try: foo() ... except Exception as err: ... print(err) ... 'staticmethod' object is not callable >>> Foo.foo() or maybe clearer: >>> @staticmethod ... def foo(): pass ... >>> def bar(): pass ... >>> class Foo: ... foo = foo ... bar = bar ... >>> Foo.bar is bar True >>> Foo.foo is foo False How would you explain that without mentioning the descriptor protocol? -- https://mail.python.org/mailman/listinfo/python-list
