问题

I am new to python and am doing a small text-based game in python. The objective is to be able to move room to room. I keep receiving a key error as python isn't recognizing one of the rooms. After I reach the living room I am then given a key error that says this:

if command in rooms[current_room].keys():
KeyError: 'Living room'

rooms = {
        'Entrance room': {'East': 'Master Bedroom'},
        'Master Bedroom': {'North': 'Family room'},
        'Family room': {'East': 'Dining Room', 'South': 'Master Bedroom'},
        'Dining Room': {'South': 'Living room', 'West': 'Family room'},
        'Living Room': {'South': 'Kitchen'},
        'Kitchen': {'South': 'Secret room', 'West': 'Master bedroom'},
        'Secret Room': {'West': 'Dungeon', 'North': 'Kitchen'},
        'Dungeon': {'East': 'Secret room'}
}
instructions = 'Welcome to the dragon slayer game, reach the dungeon to win. To move type: go North, go East, go West, go South'
directions = ['go North', 'go South', 'go East', 'go West']
print(instructions)
current_room = 'Entrance room'
while True:
    if current_room == 'Dungeon':
        print('Congratulations! You have reached the Dungeon and defeated the Dragon!')
        break
    
    print('You are in the {}.'.format(current_room))
    
    command = input('\nWhat do you want to do? ')  
    if command in directions:
        command = command.split()[1]
        if command in rooms[current_room].keys():
            current_room = rooms[current_room][command]
            print(current_room)
        else:
            
            print('You can't go that way!')
    
    elif command == 'exit':
        print('Thanks for playing!')
        break
    
    else:
        print('Invalid input')

Python字典的键是区分大小写的。你正在检查的是'Living room'而不是字典中存在的'Living Room'。请注意，字母'r'应该是大写的。

英文:

Python dictionary keys are case-sensitive. You are checking for 'Living room' instead of 'Living Room' which is present in the dictionary. Note that the letter 'r' should be a capital.
