int object 不是可迭代的 python 问题

Question

所以我不断得到一个

  File "main.py", line 77, in <module>
    dealer_cards_total = sum(dealer_cards)
TypeError: 'int' object is not iterable

我尝试了各种“解决方案”并尝试分析其他与我有相同错误的程序，但我似乎找不到任何东西，我根据程序使用一长串标签标记了错误的来源，这里是代码：

import random
import time



Ace = 11
Jack = 10
Queen = 10
King = 10


cards = [Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King]


e = 0
Ace_21 = False
player_bal = 0
dealer_bal = 0
player_cards = []
dealer_cards = []
player_cards_total = 0
dealer_cards_total = 0
card = ''
move = ''
moves = 0

def get_card():
  return(int(cards[random.randrange(1, 13)]))


dealer_cards =  [get_card()]
player_cards = [get_card(), get_card()]
player_cards_total = sum(player_cards)


def get_move():
  
  if moves == 0:
    print('\nDealer\'s cards: ', dealer_cards)
    print('Your cards: ', player_cards,'\nTotal: ', player_cards_total)
  move = input('Chose your next move: ')
  if move in ['h', 'Hit']:
    move = 'hit'
  elif move in ['s', 'Stand']:
    move = 'stand'
  return(move)



while player_cards_total < 21:
  player_cards_total = sum(player_cards)
  dealer_cards_total = sum(dealer_cards)
  if player_cards_total > 20:
    print('\n\n//////////////////////////\nDealer\'s cards: ', dealer_cards)
    print('Your cards: ', player_cards,'\nTotal: ', player_cards_total, '\n//////////////////////////')
    print('\nBUST\n')
    break
  move = get_move()
  
  if move == 'hit':
    player_cards.append(get_card())
  else:
    break

if player_cards_total > 21:                66
   print('You lose!!!')                    67
elif player_cards_total == 21:             68
  print('Great job, you win')              69

  while dealer_cards_total < 20:           72
    if e == 0:                             73
      dealer_cards.append(get_card())      74
      e = 1                                75
    print(dealer_cards)                    76
    dealer_cards_total = sum(dealer_cards) 77
    dealer_cards = get_card()              78
#####################################################
if dealer_cards_total == 21:
  print('YOU LOSE')
elif dealer_cards_total > 21:
  print('DEALER BUSTED\nYOU WIN!!!')
elif dealer_cards_total > player_cards_total and dealer_cards_total < 22:
  print('YOU LOSE')
else:
  print('YOU WIN')

这可能是一个简单的解决方法，但我是个初学者，我以前没有遇到过这个问题

Answer 1

错误发生在这些行中：

dealer_cards_total = sum(dealer_cards) 
dealer_cards = get_card()              

这样做的原因是 sum() 需要一个列表。

但是，get_card() 返回一个 integer。因此，在第一次迭代之后，dealer_cards 从列表更改为 integer。

似乎您在脚本开头就考虑到了这一点：

dealer_cards =  [get_card()]

在不评估脚本的 rest 的情况下，似乎至少解决方案应该位于某个地方，确保 dealer_cards 仍然是一个列表。
