Text based command line blackjack. Hit and Stand are the only available options. Clean, commented code. Comment out any "clear()" statements you see if you want to run it in Idle.

Discussion
Why text blackjack? I wanted to make my first complicated program. I was watching Pirates of Silicon Valley and I got to the scene where one guy goes "I just made blackjack!" and then I wanted to make blackjack.
Issues: *Occasional IndexError. A try/except statement should help fix that.

an oo version?? i think it would be easier to understand and even funner to program if you used an object oriented aproach with class's give me a couple days and i'll submit one :)
and pirates of silicon valley rocked :)
Fun game. I think there is a problem in the following sequence.
dealPlayer = deck[r.randint(1, len(deck)-1)] player.append(dealPlayer) deck.pop(dealPlayer)
dealDealer is a card value, but the list pop() is an offset, and here refers the position of the card in the deck. The effect is that the card that is pop'ed is not the one that has been delt.
I enjoyed the game (thanks Mike) so has a go at a re-write:
import random as r
class deck_of_cards:
def __init__(self): self.cards = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10]*4
def random_card_from_deck(self): # select a random card in the deck position_in_deck = r.randint(0, len(self.cards)-1) # take the card from the deck card = self.cards[position_in_deck] self.cards.pop(position_in_deck) return card
class hand:
def __init__(self,owner="Player"): self.cards = [] self.owner = owner
def showHand(self): if self.owner == "Player": print "Your Hand : (%s) Totals: %d" % (self.cards,self.tally()) #If this instance belongs to the dealer then show dealers first card elif self.owner == "Dealer": print "The Dealer is showing %s " % self.cards[1] else: print "I'm confused about who owns this hand"
def append(self,card): self.cards.append(card)
def tally(self): #total the value of the cards in this hand hand = 0 for i in self.cards: hand += i return hand
def newgame(): #Lets play !! print "dealing new cards" global deck, dealer_hand , player_hand deck = deck_of_cards() dealer_hand = hand("Dealer") player_hand = hand("Player")
Give player and dealer 2 cards to start the game for i in range(2):
dealer_hand.append(deck.random_card_from_deck()) player_hand.append(deck.random_card_from_deck())
newgame() c = 'y' while c != 'q': player_hand.showHand() dealer_hand.showHand() c = raw_input("[H]it [S]tand [Q]uit: ").lower()
if c == 'h': # Hit player_hand.append(deck.random_card_from_deck())
if not dealer_hand.tally() > 17: #Dealer's strategy. dealer_hand.append(deck.random_card_from_deck())
if player_hand.tally() > 21: print "You BUST!" newgame()
if dealer_hand.tally() > 21: print "Dealer Busts!" newgame()
elif c == 's': # Stand if player_hand.tally() > dealer_hand.tally(): print "You Win!!" newgame() else: print "You Loose!!"
elif c == 'q': # Quit gb = raw_input("Toodles. [Hit Enter]")
else: print "Invalid choice."
