蟒蛇井字問題

Question

我是新來的編碼，最近開始學習python。我的第一個挑戰是建立一個tic tac toe遊戲。下面是我的遊戲代碼，除了當我想重新開始遊戲或結束遊戲時，循環不會中斷或遊戲無法啓動，所有的一切都運行正常。任何人都可以弄清楚我的代碼有什麼問題。謝謝！

Matrix = [[' ' for i in range(3)]for j in range(3)] 
for i in Matrix: 
    print(i) #this is the 3x3 board 

def check_done(value): #this is to check if the player has won the game 
    for a in range(0,3): 
     if Matrix[0][a]==Matrix[1][a]==Matrix[2][a]==value\ 
     or Matrix[a][0]==Matrix[a][1]==Matrix[a][2]==value: 
      print ('won') 
      return True 
     #when the vertical column or horizontal row is equal, the  
     player won the game 

     if Matrix[0][0]==Matrix[1][1]==Matrix[2][2]==value\ 
     or Matrix[2][0]==Matrix[1][1]==Matrix[0][2]==value: 
      print('won') 
      return True 
     #when the diagonal rows are equal, the player won the game 

     if ' ' not in Matrix[0] and ' ' not in Matrix[1] and ' ' not in  
     Matrix[2]: 
      print('draw') 
      return True 
     #when every grid is filled in the board and no win criteria is 
     fulfilled, it is a draw 
    return False 

def replay(): #this is to determine if the player wants to restart or 
       end the game 
    command =input('Enter r to restart, or e to end game: ') 
    while True: 
    if command == 'r': 
     player1_input() 

    if command == 'e': 
      return 
      break 

    else: 
     print('Invalid command.') 


def player1_input(): #this is an input function to allow players to   
         position their next move 
    print('Player 1 insert your name here') 
    name1=input() 
    print('player 2 insert your name here') 
    name2=input() 
    while True: 
     inputValid = False 
     while inputValid == False: 
     print(name1,'please place x coordinates') 
     xinput=int(input()) 
     print(name1,'please place y coordinates') 
     yinput=int(input()) 
     if yinput >= 0 & yinput <= 2 & xinput >=0 & xinput <= 2: 
      if Matrix[yinput][xinput] == ' ': 
       Matrix[yinput][xinput] = 'X' 
       for i in Matrix: 
        print(i) 
       if check_done('X'): 
        print(name1,'won') 
        replay() 
       inputValid = True 

    inputValid = False 
    while inputValid == False: 
     print(name2,'please place x coordinates') 
     xinput=int(input()) 
     print(name2,'please place y coordinates') 
     yinput=int(input()) 
     if yinput >= 0 & yinput <= 2 & xinput >=0 & xinput <= 2: 
      if Matrix[yinput][xinput] == ' ': 
       Matrix[yinput][xinput] = 'O' 
       for i in Matrix: 
        print(i) 
       if check_done('O'): 
        print(name2,'won') 
        replay() 
       inputValid = True 

return True 

Answer 1

這是困難的，因爲它發佈到閱讀的代碼。但在我看來，你的真實是一個無限循環。我沒有看到任何突破，允許你退出而

Answer 2

主遊戲的while循環運行無限。
要解決該問題，您可以使用continue_game標誌。
一個簡單的例子：

def player1_input(): 
    # rest of the code 

    continue_game = True 
    while continue_game: 
     # logic for the game 

     continue_game = replay() 

def replay(): 
    # Returns true or false on user input. 

    while True: 
     command = raw_input('...') 
     if command == 'r': 
      return True 

     elif command == 'e': 
      return False 

     else: 
      print ('Invalid command') 

方法replay可以返回一個布爾值作爲基於用戶輸入approriate。

此外，請注意，如果遊戲應該重新啓動，您必須用空值重新初始化矩陣。
