Python Object return a list

Question

I have a Deck class from which i create a deck Object:

class Deck:
  cards = []

deck = Deck()

How can I make the deck object to return the cards list when called?

print(deck)

# or

for card in deck:
  # do

Without having to always call deck.cards?

Answer 1

You could define __iter__ in class Deck:

class Deck:
    def __init__(self):
        self.cards = [1, 2, 3]

    def __iter__(self):
        for i in self.cards:
            yield i


deck = Deck()
for card in deck:
    print(card)

And this print:

1
2
3
