Question

我已经模拟了Monty Hall游戏，我想通过用户输入的内容重复以下代码。我是一个非常新手的程序员，所以请耐心等待。我只是不知道我是否正确放置了for循环。

下面是我的代码，我想告诉它通过for循环运行剩余代码v的次数，用户之前输入。在这种情况下v是2.我得到一个TypeError，然而，它只运行一次，这种情况随时发生v>1：

表示范围内的t（1，v + 1）

print('Game',t)
  doors = [1,2,3]
  prizes = ['C','G1','G2']
  while valid == True:
    random.shuffle(prizes)
    initial_doors = list(zip(doors,prizes))
    doors = initial_doors[:]
    print('Doors are Set Up as:',doors)
    user = int(input('Select door 1, 2, or 3:\n'))
    user = user - 1
    (a,b)=doors[0]
    (c,d)=doors[1]
    (e,f)=doors[2]
    if user == 0:
      selected_door = a
      print('You selected door', selected_door)
    elif user == 1:
      selected_door = c
      print('You selected door', selected_door)
    elif user == 2:
      selected_door = e
      print('You selected door', selected_door)
      user_door = doors.pop(user)
    valid = False

  monty_door = [i for i, j in doors if 'G' in j] # This is where the error occurs
  monty_door = str(monty_door)
  monty_door = monty_door[1]
  monty_door = int(monty_door)
  print('Monty selected door', monty_door)

  car_door = [i for i, j in initial_doors if 'C' in j]
  car_door = str(car_door)
  car_door = car_door[1]
  car_door = int(car_door)

  if car_door != selected_door:
    win = 'switch'
    print('Player should', win, 'to win.')
  elif car_door == selected_door:
    win = 'stay'
    print('Player should', win, 'to win')

输出在下面，它应该在下面有另一个迭代。在询问用户要运行多少测试后，您会看到v=2，并在最后打印错误：

How many tests should we run? Type Exit to exit: 2
Game 1
Doors are Set Up as: [(1, 'G1'), (2, 'C'), (3, 'G2')]
Select door 1, 2, or 3:
 2
You selected door 2
Monty selected door 1
Player should stay to win
Game 2 # Error message below, line 58 is commented above
Traceback (most recent call last):
  File "python", line 58, in <module>
  File "python", line 58, in <listcomp>
TypeError: 'int' object is not iterable

Answer 1

你的问题似乎是你在第一场比赛结束时设置valid = False，然后在第二场比赛中你没有进入你的while循环而且门只是[1,2,3]这解释了你得到的错误。

for循环未运行指定的次数 - TypeError：＆＃39; int＆＃39;对象不可迭代
