Question

我是python的新手。我正在构建一个Tic tac toe游戏并使用地图在板上存储（x或o）的值。我代表董事会作为地图。然后我设计了一个功能，每次移动时都会检查玩家是否拥有一个游戏。但是我得到了KeyError。我真的不明白为什么？

board = {'1':'','2':'','3':'','4':'','5':'','6':'','7':'','8':'','9':''}    
def win_lose_draw(board, player):
    global number_of_moves
    if (number_of_moves <= 9 and 
            board[1] == board[2] == board[3] == player or 
            board[4] == board[5] == board[6] == player or 
            board[7] == board[8] == board[9] == player or 
            board[1] == board[4] == board[7] == player or 
            board[2] == board[5] == board[8] == player or 
            board[3] == board[6] == board[9] == player or 
            board[1] == board[5] == board[9] == player or 
            board[3] == board[5] == board[7] == player):
        print 'Player ', player, ' is the winner'
    elif number_of_moves == 9:
        print 'The game is a draw'    
def move ():
    move = raw_input("Where do you want to place your sign ?")
    global board
    if x_turn == True:
        if board[move] == 'x' or board[move] == 'o':
            print 'Place already taken, can not be overwritten'
        else:
            board[move] = 'x'
            print_board()
            win_lose_draw(board, 'x')
            decrement_moves()
    elif o_turn == True:
        if board[move] == 'x' or board[move] == 'o':
            print 'Place already taken, can not be overwritten'
        else:
            board[move] = 'o'
            print_board()
            win_lose_draw(board, 'o')
            decrement_moves()
    set_turn()

KeyError: 1

Answer 1

你的地图的键是str的类型（'1'，'2'，...），但你查询int为board [1]，board [2]，...

比较单个地图python中的值
