简单井字格游戏python代码

以下是一个简单的井字格游戏 Python 代码示例：

# 定义井字格游戏的棋盘
board = ["-", "-", "-",
         "-", "-", "-",
         "-", "-", "-"]

# 定义当前玩家
current_player = "X"

# 定义游戏是否结束的标志
game_over = False

# 定义游戏胜利的可能组合
win_combinations = [(0, 1, 2), (3, 4, 5), (6, 7, 8),
                    (0, 3, 6), (1, 4, 7), (2, 5, 8),
                    (0, 4, 8), (2, 4, 6)]

# 打印游戏棋盘
def print_board():
    print(board[0] + " | " + board[1] + " | " + board[2])
    print(board[3] + " | " + board[4] + " | " + board[5])
    print(board[6] + " | " + board[7] + " | " + board[8])

        flip_player()
    if current_player == "X" or current_player == "O":
        print(current_player + " 赢了！")
    else:
        print("平局！")

# 处理玩家输入

        position = int(position) - 1
        if board[position] == "-":
            valid = True
        else:

    board[position] = player
    print_board()

    global game_over
    if "-" not in board:
        game_over = True
        return True
    else:

# 切换玩家
