Question

Hi
I have created a List of Objects. Each object contains a Set. I want to update the set’s contents for all the objects in the list. The code that i wrote to accomplish this is

class Player:
    name = ""
    cardsInHand = set()
    hasBid = False
    def __init__(self, name):
        self.name = name 

class CardDeck:
    deck = []

    def __init__(self):
        for i in range(39) :
        if i%10>0 and i%10<9 :
                self.deck.append(i)

    def dealCards(self,player):
        cardIndex = 0
        for tempPlayer in player:
            for j in range(4): # since want to add four elements at a time
                tempPlayer.cardsInHand.add(self.deck.pop(cardIndex))
                cardIndex = cardIndex +1

in the main method I am calling the above classes with the following code

players = []
players.append(Player("Player0"))
players.append(Player("Player1"))
players.append(Player("Player2"))
players.append(Player("Player3"))

cards.dealCards(players)

The problem is that dealCards method adds the elements to all the sets of objects. Instead of 4 elements in each object’s set, I endup with same 16 elements in each objects’s set?
I am new to python, am i doing something wrong ?

You’re creating class attributes.

class Player:
    def __init__(self, name):
        self.name = name 
        self.cardsInHand = set()
        self.hasBid = False
