I’m new to python and I’m programming the Blackjack game in python with a friend of mine. I’m getting Keyerror:0 on this lines:

card1=random.choice(cards)
card2=random.choice(cards)

Is it a writing mistake or something bigger? Please help me

For context, here’s the part of the code with those lines, ngiocatori is the number of players and its input is before in the code:

pgiocatori=1
cards={
    1: "A",
    2: "2",
    3: "3",
    4: "4",
    5: "5",
    6: "6",
    7: "7",
    8: "8",
    9: "9",
    10: ["10", "J", "Q", "K"],
    11: "A"
}
card1=random.choice(cards)
card2=random.choice(cards)
def give_cards():
    print(f"Le carte del giocatore {pgiocatori} sono: " + str(carta1) +"; " + str(carta2))
while pgiocatori<=ngiocatori:
    give_cards()
    pgiocatori+=1
    card1=random.choice(cards)
    card2=random.choice(cards)```
