比較單個地圖中的值python

Question

我是python的新手。我正在構建一個Tic tac toe遊戲，並使用地圖將（x或o）的值存儲在棋盤上。我代表董事會作爲地圖。然後我設計了一個函數，在每次移動時都檢查一個玩家是否有一個遊戲。但是我得到了KeyError。我不明白爲什麼？地圖的

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[3] == board[5] == board[7] == player): 
     print 'Player ', player, ' is the winner' 
    elif number_of_moves == 9: 
     print 'The game is a draw'

    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'

鍵是STR（ '1'， '2'，...）的類型，但你查詢INT爲板[1]，板[2]，...
