为什么这个程序不把玩家的房间移到另一个房间？

Question

    def show_instructions():
      if __name__ == "__main__":
        while True:
          print('Dragon Text Game\n')


print('\t\t\tDragon Text Game.')
print('--------------------------------------------------------------------------------------- 
------')
print('Move commands: South, North, East, West')
print('Type "Exit" to end the game.')
print("Let's start with your name:  ")

name = input()
print(f'Good luck, {name}!')

# A dictionary for the simplified dragon text game
# The dictionary links a room to other rooms.

rooms = {
         'Great Hall': {'name': 'Great Hall', 'South': 'Bedroom',
         'text': 'You are in the Great Hall.'},
         'Bedroom': {'name': 'Bedroom', 'North': 'Great Hall', 'East': 'Cellar',
         'text': 'You are in the Bedroom.'},
         'Cellar': {'name': 'Cellar', 'West': 'Bedroom',
         'text': 'You are in the Cellar. Type "Exit" to end the game!'}
         }


directions = ['North', 'South', 'East', 'West']
current_room = rooms['Great Hall']
exit = False

# game loop
while True:
    print(current_room['text'])
    command = input('\nEnter your move: ')
    if command == 'Exit':
        if current_room['name'] == 'Cellar':
            # The game completes when the user enters Cellar Room
            print('Congratulations !!')
            print("You've completed 'Dragon Text Game'.")
        print('Thanks for playing!')
        break
    if command in directions:
        if command in current_room:
            current_room = rooms[current_room[command]]
        else:
            print(f'No door in {command} direction!')
         else:
        print('Invalid move!')

输出：

Dragon Text Game.

移动命令:南，北，东，西类型“出口”结束游戏。让我们从你的名字开始：

祝你好运，瑞布！你在大会堂里。

输入您的移动:南方无效移动！你在大会堂里。

输入您的移动:东方无效移动！你在大会堂里。

输入您的移动:退出无效移动！你在大会堂里。

输入您的移动：

一直在重复。在PyCharm中创建，因此所有缩进、空格等都是正确的，尽管您在上面看到了这些。这应该非常简单。我只需要在任何时候都能离开，从字典打电话到另一个房间。我不知道我做错了什么。谢谢!

尝试将directions更改为

directions = ['NORTH', 'SOUTH', 'EAST', 'WEST']

并将if command in directions:改为if command.upper() in directions:

您的代码当前无法工作，因为它区分大小写。如果您进入，South而不是south，您很可能可以从一个房间移动到另一个房间。通过强制所有输入都大写，可以避免此问题。为检查if command.upper() == 'EXIT'执行类似的操作
