Programming an OldMaid Card Game python

  1. Oct 29, 2016 #1
    I am having trouble removing the same cards from my hand in my game of oldMaid. this is my source:
    Mod note: Added code tags to preserve indentation, and modified code slightly (replacing index i in arrays with j.
    Code (Python):

        deck=[]
        suits = ['\u2660', '\u2661', '\u2662', '\u2663']
        ranks = ['2','3','4','5','6','7','8','9','10','J','Q','K','A']
        for suit in suits:
            for rank in ranks:
                deck.append(rank+suit)
        deck.remove('Q\u2663') # remove a queen as the game requires
        return deck

    def shuffle_deck(deck):
        '''(list of str)->None
           Shuffles the given list of strings representing the playing deck  
        '''

        random.shuffle(deck)

    #####################################

    def deal_cards(deck):

        dealer=[]
        other=[]

        half=len(deck)//2
        for j in range(half):
            dealer.append(deck[j])

        for j in range(half,len(deck)):
            other.append(deck[j])
         
        return (dealer, other)
             
    def remove_pairs(l):

        no_pairs=[]
     
        for j in range(1,len(l)):
            if l[j-1][0]!=l[j][0]:
                no_pairs.append(l[j])
             
        random.shuffle(no_pairs)
        return no_pairs

    def play_game():
         '''()->None
         This function plays the game'''

     
         deck=make_deck()
         shuffle_deck(deck)
         tmp=deal_cards(deck)

         dealer=tmp[0]
         human=tmp[1]

         print("Hello. My name is Robot and I am the dealer.")
         print("Welcome to my card game!")
         print("Your current deck of cards is:")
         print_deck(human)
         print("Do not worry. I cannot see the order of your cards")

         print("Now discard all the pairs from your deck. I will do the same.")
         wait_for_player()
       
         dealer=remove_pairs(dealer)
         human=remove_pairs(human)
     
    # main
    play_game()

    In the future, please use code tags, especially with Python code, where indentation is crucial.

    What I did was add tags like this:
    [code=python]
    <Some Python code>
    [/code]
    I also modified your code slightly, replacing array indexes of i with j. The reason for this is that our system thinks that arr[i] means that it should display arr, and then start displaying in italics.

    Regarding your question, please give more details. Where in the code are you seeing the problem?

    Also, single-letter variables are OK for loop control variables, but not OK for any other purpose. In your remove_pairs() function, what does l (letter el) represent?

    Suggestion: use a debugger or add a command so that, at the beginning of remove_pairs, you can see the cards you passed in.
