What about when the function is *static*, or when it is a method attached to a *class*... – Willem Van Onsem Oct 18 '17 at 15:38

You never really *need* to use `staticmethod` not `classmethod`, although, `classmethod` is actually useful sometimes – juanpa.arrivillaga Oct 18 '17 at 15:53

When you call a method of a python object, the object itself is automatically passed as the first parameters (usually named self)
You can change this in two ways
- annotate with
@classmethod: now, instead of the object, the class of the object is automatically passed as first argument - annotate with
@staticmethod: now, no extra argument is passed, just the ones you provided. Just like a normal python function
Classmethods are commonly used for alternative constructors. Static methods are plain functions that are put inside the class namespace, just for logical grouping.
