井字棋pycharm

井字棋是一种经典的游戏，下面是一个使用PyCharm开发的井字棋的示例代码：

# 定义一个3x3的空棋盘
board = [[' ' for _ in range(3)] for _ in range(3)]

# 打印棋盘
def print_board():
    for row in board:
        print('|'.join(row))
        print('-' * 5)

# 判断是否有玩家获胜
def check_win(player):
    # 检查行
    for row in board:
        if row.count(player) == 3:
            return True
    # 检查列
    for col in range(3):
        if [board[row][col] for row in range(3)].count(player) == 3:
            return True
    # 检查对角线
    if board[0][0] == board[1][1] == board[2][2] == player:
        return True
    if board[0][2] == board[1][1] == board[2][0] == player:
        return True
    return False

# 游戏主循环
def game_loop():
    player = 'X'
    while True:
        print_board()
        row = int(input("请输入行号（0-2）："))
        col = int(input("请输入列号（0-2）："))
        if board[row][col] == ' ':
            board[row][col] = player
            if check_win(player):
                print_board()
                print(f"玩家 {player} 获胜！")
                break
            if all(board[row][col] != ' ' for row in range(3) for col in range(3)):
                print_board()
                print("平局！")
                break
            player = 'O' if player == 'X' else 'X'
        else:
            print("该位置已经有棋子，请重新输入。")

# 开始游戏
game_loop()

这段代码使用了一个3x3的二维列表来表示棋盘，玩家可以通过输入行号和列号来下棋。程序会判断是否有玩家获胜或者平局，并在游戏结束时打印相应的信息。
