Print Out Objects Stored In A List

I am new to Python, busy creating a blackjack game. I have almost got printing out my deck of cards right, but I can't seem to iterate through all the cards stored in the list. sui

Solution 1:

Within a method, return can only be executed once, then control returns to the calling code, so you can't have a return inside a loop. One solution is to build the entire string to be printed, then return that.

If you change your code in class Deck to:

def__str__(self):
    return"\n".join(f"{card.rank} of {card.suit}"for card in self.deck)

It will return a string containing the entire deck of cards so that your print functions correctly.

Solution 2:

You could use a list comprehension to achieve the desired print of your deck of cards.

[f"{card.rank} of {card.suit}"for card in deck]

This statement would create a python list that contains string representations of the cards in your deck. Now we can turn this list of strings into one single string by using the string.join() method, which concatenates the strings in the list and delimits them with the preceding string to join.

"\n".join([f"{card.rank} of {card.suit}"for card in deck])

If you print this you would get:

Two of Hearts
Three of Hearts
Four of Hearts
Five of Hearts
Six of Hearts
Seven of Hearts
Eight of Hearts
Nine of Hearts
Ten of Hearts
Jack of Hearts
Queen of Hearts
King of Hearts
Ace of Hearts
Two of Diamonds
Three of Diamonds
Four of Diamonds
Five of Diamonds
Six of Diamonds
Seven of Diamonds
Eight of Diamonds
Nine of Diamonds
Ten of Diamonds
Jack of Diamonds
Queen of Diamonds
King of Diamonds
Ace of Diamonds
Two of Spades
Three of Spades
Four of Spades
Five of Spades
Six of Spades
Seven of Spades
Eight of Spades
Nine of Spades
Ten of Spades
Jack of Spades
Queen of Spades
King of Spades
Ace of Spades
Two of Clubs
Three of Clubs
Four of Clubs
Five of Clubs
Six of Clubs
Seven of Clubs
Eight of Clubs
Nine of Clubs
Ten of Clubs
Jack of Clubs
Queen of Clubs
King of Clubs
Ace of Clubs

And your complete code is now:

suits = ['Hearts','Diamonds','Spades','Clubs']
ranks = ['Two','Three','Four','Five','Six','Seven','Eight','Nine','Ten','Jack','Queen','King','Ace']
values = {'Two':2, 'Three':3,'Four':4,'Five':5,'Six':6,'Seven':7,'Eight':8,'Nine':9,'Ten':10,'Jack':10,'Queen':10,'King':10,'Ace':(1,11)}

playing = TrueclassCard:
    def__init__(self, suit, rank):
        self.suit = suit
        self.rank = rank

    def__str__(self):
        print(f"{self.rank} of {self.suit}")

classDeck:
    def__init__(self):
        self.deck = []
        for suit in suits:
            for rank in ranks:
                self.deck.append(Card(suit, rank))

    def__str__(self):
        return"\n".join([f"{card.rank} of {card.suit}"for card in self.deck])

deck = Deck()

print(deck)
