的Python - 类型错误：int对象不标化

Question

我有一个错误：

Traceback (most recent call last):                                                 
    File "DungeonGame.py", line 92, in <module>                                               
    possible = possibleMoves(locations["player"])                                              
    File "DungeonGame.py", line 65, in possibleMoves                                             
     if player[0][0] == 0: 
TypeError: 'int' object is not subscriptable 

这里是我的代码：

def possibleMoves(player): 
    options = ["RIGHT", "LEFT", "UP", "DOWN"] 

    if player[0][0] == 0: 
     options.remove("LEFT") 
    elif player[0][0] == 4: 
     options.remove("RIGHT")  
    elif player[0][1] == 0: 
     options.remove("DOWN") 
    elif player[0][1] == 4: 
     options.remove("UP") 

    return options 

... 

locations = {"monster" : (1, 2), "door" : (3, 2), "player" : (4, 1)} 
possible = possibleMoves(locations["player"]) 

有人能帮助我吗？

Answer 1

这就是为什么你的错误：

player[0][0] == (4, 1)[0][0] == 4[0] 

您传递locations["player"]到possibleMoves(player)，所以player == locations["player"] == (4, 1)。
