使用 while 循环使用另一个列表中的元素更新列表并找到新列表的总和

Question

我很难使用 while 循环将卡片添加到列表并不断更新总和。目前我收到一个操作数类型错误，提示我无法将列表添加到列表中。理想情况下每当玩家选择一张带有 'y' 的新牌时，列表就会更新，分数也会更新。

import random

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


def blackjack():
    should_continue = True
    player_card1 = int(random.choice(cards))
    comp_card = random.choice(cards)
    if input("Do you want to play? Type 'y' or 'n'\n") == 'y':
    
        while should_continue:
            
            add_card = int(random.choice(cards))
            player_cards = [player_card1]
            player_cards.append(add_card)
            comp_card = random.choice(cards)
            player_score = sum(player_cards)
            
            print(f"Your cards: {player_cards}, current score:{player_score}")
            print(f"Computer's first card: {comp_card}")
            if input(f"Type 'y' to get another card, type 'n' to pass:") == 'y':
                player_card1 = player_cards
                comp_card = comp_card
            else:
                should_continue = False
                #calculate()

    else:
        should_continue = False

Answer 1

您正在创建嵌套列表。卡片是这样添加的

[10, 10]
[[10, 10], 10]

所以，你不能[10, 10] + 10
我已经修复它并删除了一些死代码。考虑使用 PyCharm 之类的东西进行调试、语法检查和其他好处

import random

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


def blackjack():
    should_continue = True
    player_cards = [random.choice(cards)]
    if input("Do you want to play? Type 'y' or 'n'\n") == 'y':

        while should_continue:
            player_cards.append(random.choice(cards))
            comp_card = random.choice(cards)
            player_score = sum(player_cards)

            print(f"Your cards: {player_cards}, current score:{player_score}")
            print(f"Computer's first card: {comp_card}")
            if not input(f"Type 'y' to get another card, type 'n' to pass:") == 'y':
                should_continue = False

使用 while 循环使用另一个列表中的元素更新列表并找到新列表的总和

Using a while loop to update list with elements from another list and find the sum of new list

python
