Tic Tac Toe（井字棋）游戏win函数异常触发及未正常结束问题求助

问题原因分析 #

win函数无端触发 #

• 对角线判断逻辑缺失：第二个对角线条件仅写了board[2,0]，未和当前玩家turn做相等判断，只要该位置被占用（非0）就会触发获胜逻辑；
• 代码缩进错误：所有胜负判断的if语句后，win()和break没有缩进，导致每次落子后不管条件是否满足，都会直接执行获胜逻辑并终止游戏。

游戏未分胜负却无法结束 #

缺少平局判定逻辑：当棋盘所有位置被填满但无人获胜时，循环会一直运行，没有终止机制。

修复后的完整代码 #

from numpy import array

board = array([
    [0,0,0],
    [0,0,0],
    [0,0,0]
])

turn = 1

def win():
    print(board)
    print('\nYou Win!\n')

def draw():
    print(board)
    print('\nDraw!\n')

while True:
    print(board)

    row = int(input('Row: '))
    column = int(input('Column: '))

    # 防止重复落子
    if board[row, column] != 0:
        print("这个位置已经被占了！换一个位置吧。")
        continue

    board[row, column] = turn

    # 检查对角线获胜
    if (board[0,0] == turn and board[1,1] == turn and board[2,2] == turn) or \
       (board[0,2] == turn and board[1,1] == turn and board[2,0] == turn):
        win()
        break

    # 检查行获胜
    if (board[0,0] == turn and board[0,1] == turn and board[0,2] == turn) or \
       (board[1,0] == turn and board[1,1] == turn and board[1,2] == turn) or \
       (board[2,0] == turn and board[2,1] == turn and board[2,2] == turn):
        win()
        break

    # 检查列获胜
    if (board[0,0] == turn and board[1,0] == turn and board[2,0] == turn) or \
       (board[0,1] == turn and board[1,1] == turn and board[2,1] == turn) or \
       (board[0,2] == turn and board[1,2] == turn and board[2,2] == turn):
        win()
        break

    # 检查平局：棋盘无空位
    if not (board == 0).any():
        draw()
        break

    # 切换玩家
    turn = 2 if turn == 1 else 1

关键修复说明 #

1. 修正缩进：将win()和break移入if语句块内，仅在胜负条件满足时执行；
2. 补全对角线判断：给第二个对角线的最后一个条件加上== turn，确保三个位置都是当前玩家的棋子才判定获胜；
3. 添加平局逻辑：通过(board == 0).any()检查是否还有空位，无空位时触发平局并终止循环；
4. 增加落子校验：防止玩家在已占用位置落子，优化游戏体验；
5. 简化玩家切换：用三元表达式替代冗余的if-else，代码更简洁。
