否则：语句会导致语法错误？

Question

我一直在使用Python中的Zork风格的命令解析器，并且我遇到了else：语句的问题。我可能会遗漏一些明显的东西（不是一个非常熟练的程序员），但我无法弄清楚为什么这会导致语法错误。以下是有问题的代码：

while 1 == 1:
    room_changed = 0
    user_input = raw_input('>')
    if user_input == "check":
        test.Check()
    elif user_input == "north":
        room = test.North(X, Y, Z)
        room_changed = 1
    elif user_input == "south":
        room = test.South(X, Y, Z)
        room_changed = 1
    elif user_input == "east":
        room = test.East(X, Y, Z)
        room_changed = 1
    elif user_input == "west":
        room = test.West(X, Y, Z)
        room_changed = 1
    elif user_input == "look":
        print(ROOMS[room]['description']
    else:
        print("I don't understand")
