It's not that the language is hiding self/this so much as what manually passing those as variables represent. What you are saying is that you never need to call

  You only have to list self in the declaration, you don't have to pass the instance to itself. Borrowing masklinn's example: >>> class Foo(object): ... def __init__(self): ... self.n = 42 ... def bar(self): ... return self.n ... >>> f = Foo() >>> f.bar() 42

    Although you can also (and that can be rather neat when e.g. mapping or filtering) use the method as a function, if you get it from the class: f = Foo() Foo.bar(f) note that it will typecheck the first argument to ensure it's an instance of `Foo`, it's not a function, it's an unbound method: >>> class Bar(object): pass ... >>> b = Bar() >>> b.n = 66 >>> Foo.bar(b) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unbound method bar() must be called with Foo instance as first argument (got Bar instance instead)

      If you want to do that use the @staticmethod decorator.

        Oh just, you know, create a function... There's nothing more pointless than @staticmethod, unless it was used specifically to port code it should mark whoever used it for a whipping.
