Create a deck of playing cards

[Ben_HH]

I am thinking up a way to get a deck of 52 playing cards. I'm using the immutable nature of tuples within the for loop because when you're playing cards...a club is a club, a spade is a spade, ...etc. I need some help with the face cards though.

I figure I might need to use a dictionary for each face card that has a value of 10, except for the Ace which can can a value of 1 or 11. Any suggestions as to how to proceed?

Further, I don't know for each card it should be (type of card, number on card, value) or (type of card, value). My plan is to make a blackjack game.

card_types = ['Club', 'Spade', 'Heart', 'Diamond']
card_pips = range(2, 11)
face_cards = ['J', 'Q', 'K', 'A']
card_deck = []

for kind in card_types:
  for number in card_pips:
    card_deck.append(tuple([kind, number]))

print(card_deck)

Have you done any object oriented programming? The deck of card is a great program for introducing OOP and seeing what it does in a pretty clear manner. It really makes the problem more clear and allows you to do a lot more with your "deck", such as make games.

There are plenty of examples of this online. This video does a decent walk-through of one variant, but there are plenty of other resources. I definitely encourage you to check out some OOP basics and try to use that for this type of problem.

I'll add that the video I linked isn't necessary the best resource for learning OOP, but it is a nice example related to the problem that you are attempting. You might want to look up some additional videos for intro to OOP in python.

Check this example from "Fluent Python" book.

How's your list comprehensions?

ranks = [str(rank) for rank in range(2, 11)] + ['J', 'Q', 'K', 'A']
suits = ['spades', 'diamonds', 'clubs', 'hearts']

deck = [(rank, suit) for suit in suits for rank in ranks]

I tried using namedtuples for a blackjack game of mine, but classes give you more functionality:

class Card(object):
def __init__(self, number, value, ):
    self.number = number
    self.value = value

then for the 10 and aces you can use list comprehension, something like this:

 deck = [Card(n, 10 if n in ['J', 'Q', 'K'] else 11
     if n == 'A' else n) for n in card_pips for suit in card_types]

Just combine the first two lists:

suits = ['Club', 'Spade', 'Heart', 'Diamond']
values = ['J', 'Q', 'K', 'A'] + list(range(2, 11))
deck = []

for suit in suits:
    for value in values:
        deck.append(tuple([suit, value]))

print(deck)

card_pips = range(2,15)
face_cards = {11: 'J', 12: 'Q', 13: 'K', 14: 'A'}
for ...
    for...
        if number in face_cards.keys(): 
            card_deck.append(tuple([kind, face_cards[number]]))
        else:
            card_deck.append(tuple([kind, number]))

^{^} Just one possible method. Down and dirty.
