I followed a tutorial to code blackjack in python. It generates a deck, and plays one round of blackjack, then ends the program. Once the player and the dealer have received all of their cards, and the outcome is declared, I want to print all of the remaining cards in the deck to verify it is working properly. This way I can move on to playing with more than one deck confidently.
class Card:
def __init__(self,value,suit):
self.cost = value
self.value = ['A', '2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K'][value-1]
self.suit = '♥♦♣♠'[suit]
def price(self):
if self.cost >= 10:
return 10
elif self.cost == 1:
return 11
return self.cost
def show(self):
print('_________')
print(f'| {self.value:<2} |')
print('| |')
print(f'| {self.suit} |')
print('| |')
print(f'| {self.value:>2} |')
print('_________')

cards = []
for i in range(iteration):
card = random.choice(self.cards)
self.cards.remove(card)
cards.append(card)
return cards

class Player:

self.isDealer = isDealer

self.check_score()
if self.score > 21: #Useless
return 1
return 0

a_counter += 1
self.score += card.price()
while a_counter != 0 and self.score > 21:
a_counter -= 1

print("Player wins. Congradulations!")
self.deck.remaining()
b = Blackjack()
b.play()
Looks like a simple for loop will do the trick. All the other code in the deck class looks like it properly removes a card from the list. So:
def remaining(self):
print("Remaining cards in deck":)
for card in self.cards:
print(card)
Printing out the entire list as a whole is also a possibility.
print(self.cards)
In any case:
Just make sure that the card class has a __str__() method.
def __str__(self):
return self.suit + self.value
This function gets called whenever a string representation of the class instance is requested. So, it can be used to return a string of what that representation must be.
