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, ....)

Answer 2

This is a code example that actually works

class Card():
    def __init__(self,cardsPlayedList,cardPosition):
        self.cardsPlayedList = cardsPlayedList
        self.cardPosition = cardPosition
    #    self.cardPosition

    def getNewCard(self,cardPosition):
        cardNum = 0
        cardInList = False
        
        cardNum = random.randint(1,len(cardList)-1)          # Get random card from List - 1 to 52 
        for x in self.cardsPlayedList:
            if(cardNum == x):
                cardInList = True                            

        if(cardInList == False):
            self.cardsPlayedList.insert(self.cardPosition, cardNum)    # if card not already played then store in list
            return cardNum
        else:
            return self.getNewCard(cardPosition)
