Python Programming an OldMaid Card Game python

[garr6120]

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.

    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)

    random.shuffle(no_pairs)
    return no_pairs

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

What I did was add tags like this:

<Some Python 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 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.

Amen to that suggestion. I wrote an Insight article about the built-in Python debugger: https://www.physicsforums.com/insights/simple-python-debugging-pdb-part-1/.
