I would like some help. The goal os this function is to find if there is a pair in a set of cards and find out which are them.

I am able to reach the value with the print command, but my for loop is broken.

def check_pair(cards):
    print(cards)  #works
    print(cards[1][1]) #works
    for i in cards:
        ranks.append(cards[i][0])
    pairs = {k:ranks.count(k) for k in ranks}
    return pairs

community_cards = [(1, 'd'), (2, 'h'), (1, 'h')]

print(f'Checking pair: {check_pair(community_cards)}')

File “e:Python_BooksPython Crash Coursepoker.py”, line 42, in check_pair
ranks.append(cards[i][0])
~~~~~^^^
TypeError: list indices must be integers or slices, not tuple
