井字棋python代码

以下是一个简单的井字棋游戏的Python代码示例：

# Tic-Tac-Toe 井字棋游戏

# 全局常量
X = "X"
O = "O"
EMPTY = " "

# 初始化游戏棋盘
board = [EMPTY] * 9

# 打印游戏棋盘
def print_board(board):
    print("--")
    for i in range(3):
        print("|", board[i*3], "|", board[i*3+1], "|", board[i*3+2], "|")
        print("--")

# 询问是否继续
def ask_yes_no(question):
    response = None
    while response not in ("y", "n"):
        response = input(question).lower()
    return response

# 主游戏循环
def main():
    print("Welcome to Tic-Tac-Toe!")
    print_board(board)
    while True:
        # 玩家X下棋
        move = int(input("Player X, enter your move (0-8): "))
        board[move] = X
        print_board(board)
        # 判断是否获胜
        if (board[0] == board[1] == board[2] == X) or \
           (board[3] == board[4] == board[5] == X) or \
           (board[6] == board[7] == board[8] == X) or \
           (board[0] == board[3] == board[6] == X) or \
           (board[1] == board[4] == board[7] == X) or \

            print("Player X wins!")
            break
        # 判断是否平局
        if EMPTY not in board:
            print("It's a tie!")
            break
        # 玩家O下棋

           (board[1] == board[4] == board[7] == O) or \
           (board[2] == board[5] == board[8] == O) or \
           (board[0] == board[4] == board[8] == O) or \
           (board[2] == board[4] == board[6] == O):
