首先

GomokuGame 类的构造函数 __init__ 初始化游戏。board_size 参数默认为 15，表示棋盘大小。board 是一个二维列表，代表棋盘上的状态。current_player 记录当前玩家，初始为 'X'。winner 记录胜利者，初始为 None。

class GomokuGame:
    def __init__(self, board_size=15):
        self.board_size = board_size
        self.board = [[' ' for _ in range(board_size)] for _ in range(board_size)]
        self.current_player = 'X'
        self.winner = None

print_board 方法用于打印当前棋盘的状态。首先，它打印列索引。然后，遍历每一行打印出当前行的棋子状态。

    def print_board(self):
        print("  " + " ".join(str(i) for i in range(self.board_size)))
        for i in range(self.board_size):
            print(str(i) + " " + " ".join(self.board[i]))
        print()

make_move 方法用于玩家落子。如果指定位置为空，将当前玩家的标记放置在该位置。然后调用 check_winner 方法检查是否有胜利者。最后，切换当前玩家。

    def make_move(self, row, col):
        if self.board[row][col] == ' ':
            self.board[row][col] = self.current_player
            if self.check_winner(row, col):
                self.winner = self.current_player
            self.current_player = 'X' if self.current_player == 'O' else 'O'
            return True
        return False

check_winner 方法用于检查是否有玩家获胜。它通过检查当前位置的四个方向来判断是否有五个连续相同的棋子。如果存在，则返回 True，表示有玩家获胜。

    def check_winner(self, row, col):
        directions = [(0, 1), (1, 0), (1, 1), (1, -1)]
        for dr, dc in directions:
            count = 1
            for i in range(1, 5):
                r, c = row + i * dr, col + i * dc
                if 0 <= r < self.board_size and 0 <= c < self.board_size and self.board[r][c] == self.current_player:
                    count += 1
                else:
                    break
            for i in range(1, 5):
                r, c = row - i * dr, col - i * dc
                if 0 <= r < self.board_size and 0 <= c < self.board_size and self.board[r][c] == self.current_player:
                    count += 1
                else:
                    break
            if count >= 5:
                return True
        return False

play 方法是游戏的主循环。它持续运行直到有玩家获胜。在每一轮中，它打印当前棋盘，然后获取玩家输入的行和列，进行落子操作。如果落子无效，则要求玩家重新输入。如果有玩家获胜，则打印胜利信息并结束游戏。

    def play(self):
        while not self.winner:
            self.print_board()
            try:
                row = int(input("玩家{}的回合，请输入你要下的行数: ".format(self.current_player)))
                col = int(input("请输入你要下的列数: "))
                if 0 <= row < self.board_size and 0 <= col < self.board_size:
                    if self.make_move(row, col):
                        if self.winner:
                            self.print_board()
                            print("玩家{},你赢了".format(self.winner))
                            break
                    else:
                        print("无效移动。再试一次。")
                else:
                    print("输入无效。再试一次。")
            except ValueError:
                print("输入无效。输入一个数字。")

在代码的末尾，通过这个条件判断，确保仅在直接运行该脚本时才会执行创建游戏对象并开始游戏。

if __name__ == "__main__":
    game = GomokuGame()
    game.play()

下面是完全代码，可以直接复制运行

    def __init__(self, board_size=15):

        print()

        return False
