如何格式化井字游戏板（Python）

Question

本质上，我正在尝试格式化井字棋板，因此它以带有网格线的 3 x 3 图案打印。

首先，我尝试对网格进行硬编码，但后来它不可编辑。现在我创建了一个列表列表，我试图迭代每个元素，并为每个元素打印与其相邻的行。然而，当我这样做时，我遇到了“TypeError: can only concatenate str (not “list”) to str”，现在我不确定该怎么做。

相关代码：

class Tictactoe:

    def __init__(self, playerone, playertwo,):
        self.playerone = playerone
        self.playertwo = playertwo
        
        

    def newBoard(self):
        # creates new board
        return [[None, None, None],
                 [None, None, None],
                 [None, None, None]
                 ]
        
        
        
        


    def renderBoard(self):
        #todo: prints current state of board
        board = self.newBoard()
        for i in board:
            print("|" + i + "|")



    def getMove(self):
        #todo: get inputfor current player's move
        pass

    def makeMove(self):
        #todo: code the current player's move
        pass

    def getWinner(self):
        #todo write win conditions
        '''if player one marks 3 in a row, player one wins, end game
        if player two marks 3 in a row, player 2 wins, end game
        '''
        pass

    def resetButton(self):
        #todo: create a reset button that clears the board.
        pass

    def runGame(self):
        #todo: write code that starts the game.
        pass

    def isBoardFull(self):
        #todo: write code that checks if board is full
        pass


def main():
    test = Tictactoe("playerone", "playertwo")
    test.renderBoard()

if __name__ == '__main__':
    main()

解决方案

def newBoard(self):
    # creates new board
    return [['x', 'o', ' '], # add markers to board
            [' ', ' ', ' '],
            [' ', ' ', ' ']]

def renderBoard(self):
    #todo: prints current state of board
    board = self.newBoard()
     
    print(f" {board[0][0]} | {board[0][1]} |  {board[0][2]} ")
    print("---+---+---")
    print(f" {board[1][0]} | {board[1][1]} |  {board[1][2]} ")
    print("---+---+---")
    print(f" {board[2][0]} | {board[2][1]} |  {board[2][2]} ")

您遇到的问题是您试图打印一行板，但

+

操作员不知道如何处理这些类型。因此，为了简单起见，我对电路板进行了硬编码，但我使用

f"{}"

以便可以打印出电路板的当前状态。现在，您可以通过将索引传递到游戏板来更新板。
