五子棋的白色棋子有112枚，黑子有113枚，而围棋白色棋子有180枚，黑色棋子181枚。

嘿嘿，我猜很多人都不清楚吧？！

今天小编带大家深入了解五子棋，做一款代码版本的五子棋小游戏给大家，不仅能对战电脑人机，

还能跟你的小伙伴儿一起联机对抗哦~

 1）游戏界面

class gameStartUI(QWidget):
    def __init__(self, parent=None, **kwargs):
        super(gameStartUI, self).__init__(parent)
        self.setFixedSize(760, 650)
        self.setWindowTitle('五子棋游戏对战')
        self.setWindowIcon(QIcon(cfg.ICON_FILEPATH))
        # 背景图片
        palette = QPalette()
        palette.setBrush(self.backgroundRole(), QBrush(QPixmap(cfg.BACKGROUND_IMAGEPATHS.get('bg_start'))))
        self.setPalette(palette)
        # 按钮
        # --人机对战
        self.ai_button = PushButton(cfg.BUTTON_IMAGEPATHS.get('ai'), self)
        self.ai_button.move(250, 200)
        self.ai_button.show()
        self.ai_button.click_signal.connect(self.playWithAI)
        # --联机对战
        self.online_button = PushButton(cfg.BUTTON_IMAGEPATHS.get('online'), self)
        self.online_button.move(250, 350)
        self.online_button.show()
