无法弄清楚为什么我的列表索引超出范围

Question

我创建了一个函数来计算带有 for 循环的 21 点手牌的价值，但它一直告诉我索引超出范围，我不知道为什么

我尝试从“for card in total_cards”切换到“for card in range(0, len(total_cards))”希望这能解决我的问题，但我一直遇到同样的错误。由于这两个错误似乎都源于函数，我在这里缺少什么？谢谢大家。

import random

def count_total(total_cards):
    total = 0
    for card in total_cards:
        total += total_cards[card]
    return total


cards = [11, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10]

house_cards = []
player_cards = []
for i in range (1, 5):
    if i % 2 == 0:
        player_cards.append(cards[random.randint(0, len(cards) - 1)])
    elif i % 2 != 0:
        house_cards.append(cards[random.randint(0, len(cards) - 1)])

print(house_cards)
print(player_cards)

should_continue = True
while should_continue:
    action = input("Typr 'y' to ask for a card or 'n' to stop: ")
    if action == "n":
        should_continue = False
        break
    elif action == "y":
        player_cards.append(cards[random.randint(0, len(cards) - 1)])
        count_total(player_cards)
        if count_total(player_cards) > 21:
            should_continue = False
            print("You have gone over 21, you lost!")
            break

这就是问题：

for card in total_cards:
    total += total_cards[card]

您不需要索引到集合中 - for 循环正在为您做这件事。只需将其更改为：

for card in total_cards:
    total += card
