Python Recursion within Class

Question

I just learn python today, and so am thinking about writing a code about recursion, naively. So how can we achieve the following in python?

class mine:
    def          


        

Answer 1

Each method of a class has to have self as a first parameter, i.e. do this:

def recur(self, num):

and it should work now.

Basically what happens behind the scene is when you do

instance.method(arg1, arg2, arg3, ...)

Python does

Class.method(instance, arg1, arg2, arg3, ....)
