我在python3中不断得到montyhall游戏刺激器的错误输出

Question

我正在尝试重新创建Monty Hall游戏（here is a description of the game) 在这里，它会要求用户输入一个数字（我的代码要求'输入一个随机种子'）开始，如果用户没有输入一个数字，游戏将显示一个错误消息。如果用户输入了一个数字，游戏就开始了。然后游戏会问用户他们想测试游戏多少次，所以如果用户说5次，那么游戏会重复5次，一旦完成所有5个游戏，它会再次问用户。但是，如果用户输入一个字符串/非数字，比如“5”，那么游戏应该要求用户输入一个数字，直到用户最终输入一个数字。你知道吗

以下是输入的示例

25
5
exit

这里是输出应该是什么

Enter Random Seed:
Welcome to Monty Hall Analysis
Enter 'exit' to quit.
How many tests should we run?
Game 1
Doors: ['G', 'C', 'G']
Player Selects Door 1
Monty Selects Door 3
Player should switch to win.
Game 2
Doors: ['C', 'G', 'G']
Player Selects Door 1
Monty Selects Door 2
Player should stay to win.
Game 3
Doors: ['G', 'C', 'G']
Player Selects Door 2
Monty Selects Door 1
Player should stay to win.
Game 4
Doors: ['C', 'G', 'G']
Player Selects Door 1
Monty Selects Door 2
Player should stay to win.
Game 5
Doors: ['G', 'C', 'G']
Player Selects Door 3
Monty Selects Door 1
Player should switch to win.
Stay Won 60.0% of the time.
Switch Won 40.0% of the time.
How many tests should we run?
Thank you for using this program.

以下是我的程序输出的内容

Enter Random Seed:
Welcome to Monty Hall Analysis
Enter 'exit' to quit.
How many tests should we run?
Please enter a number:
How many tests should we run?
Traceback (most recent call last):
  File "monty.py", line 16, in <module>
    tests = int(input('How many tests should we run?\n'))
EOFError: EOF when reading a line

这是我的代码

import random
G=0
G2=0
C=0
try:    
    random_seed = input('Enter Random Seed:\n')
    random_seed = int(random_seed)
    print('Welcome to Monty Hall Analysis')
    exit = input("Enter 'exit' to quit.\n")
    while True:
            if exit == 'exit':
                    print('Thank you for using this program.')
                    break
            try:
                    tests = int(input('How many tests should we run?\n'))
                    tests = int(tests)
            except ValueError:
                    print('Please enter a number:')
                    continue
            select_door = ['G', 'C', 'G']
            random.shuffle(select_door)
            player_door = int(input('Doors: '+str(select_door)))
            if random.shuffle(select_door) == "['G', 'C', 'G']":
                    G = 1
                    C = 2
                    G2 = 3
            elif random.shuffle(select_door) == "['C', 'G', 'G']":
                    C = 1
                    G = 2
                    G2 = 3
            elif random.shuffle(select_door) == "['G', 'G', 'C']":
                    G = 1
                    G2 = 2
                    C = 3
            if player_door == C:
                    print('Player should stay to win')
            else:
                    print('Player should switch to win')
            doors = [1 , 2 , 3]
            random.choice(doors)
            print('Player Selects Door: ', player_door)
            print('Monty Selects Door: ', random.choice(doors)) 
except ValueError:
    print('Seed is not a number!')

抱歉，如果我的代码是真的很糟糕或如果它没有意义。我是新来的程序员。还有，我只是想让实际的游戏工作之前，我可以在%停留赢得和%开关赢得部分工作。你知道吗

你把这段代码放在一个无限循环中，这就是为什么每次都调用它

try:
    tests = int(input('How many tests should we run?\n'))
    tests = int(tests)
except ValueError:
    print('Please enter a number:')
    continue

我的解决办法是：

import random
G=0
G2=0
C=0
try:    
    random_seed = input('Enter Random Seed:\n')
    random_seed = int(random_seed)
    print('Welcome to Monty Hall Analysis')
    exit = input("Enter 'exit' to quit.\n")
    while True:
        if exit == 'exit':
                print('Thank you for using this program.')
                break
        try:
                tests = int(input('How many tests should we run?\n'))
                tests = int(tests)
        except ValueError:
                print('Please enter a number:')
                continue
        stay_cases = 0
        switch_cases = 0
        for _ in range(tests):
            select_door = ['G', 'C', 'G']
            random.shuffle(select_door)
            player_door = int(input('Doors: '+ str(select_door)))
            if random.shuffle(select_door) == "['G', 'C', 'G']":
                    G = 1
                    C = 2
                    G2 = 3
            elif random.shuffle(select_door) == "['C', 'G', 'G']":
                    C = 1
                    G = 2
                    G2 = 3
            elif random.shuffle(select_door) == "['G', 'G', 'C']":
                    G = 1
                    G2 = 2
                    C = 3
            if player_door == C:
                    print('Player should stay to win')
                    stay_cases += 1
            else:
                    print('Player should switch to win')
                    switch_cases += 1
            doors = [1 , 2 , 3]
            random.choice(doors)
            print('Player Selects Door: ', player_door)
            print('Monty Selects Door: ', random.choice(doors))
        print('Stay Won {}% of the time.'.format((stay_cases/tests) * 100))
        print('Switch Won {}% of the time.'.format((switch_cases/tests) * 100))
except ValueError:
    print('Seed is not a number!')

我添加了for _ in range(tests)，主游戏引擎应该运行tests次。你知道吗

我还实现了Stay won ... of the time

我给你的代码应该做的工作，但是，它会崩溃，如果用户选择一个门不是其中一个提供的门。为了避免这种情况，可以使用if player_door not in doors检查用户选择是否是所提供的选择之一。你知道吗
