while True: screen.fill(255,255,255) pygame.draw.rect(screen, (195, 195, 195), (30,20,740,550)) pygame.display.update()

您的代码看起来几乎正确，但在`screen.fill()`函数中填充颜色时，需要将RGB值作为一个元组传递给函数。修改代码如下：

while True:
    screen.fill((255, 255, 255))
    pygame.draw.rect(screen, (195, 195, 195), (30, 20, 740, 550))
    pygame.display.update()

这样，窗口的背景将被填充为白色 `(255, 255, 255)`，并且将绘制一个颜色为 `(195, 195, 195)` 的矩形 `(30, 20, 740, 550)`。

请确保在代码中包含了初始化Pygame和创建窗口的相关代码。并且在适当的位置添加退出游戏的逻辑，如按下关闭窗口按钮时调用`pygame.quit()`和`sys.exit()`。

希望这能帮到您！如果您有任何其他问题，请随时提问。

在代码中添加以下代码可以在游戏界面上添加一条分割线：

# 画一条分割线
pygame.draw.line(screen, [0, 0, 0], [0, 240], [640, 240], 5)

这是一个使用 Pygame 库制作的简单的翻牌游戏示例代码。程序首先导入 Pygame 和 sys 模块，然后定义了一个 Card 类，表示一张卡牌，其中包括两个图片和位置信息等属性。Card 类还定义了 flip() 方法用于翻牌，并在 update() 方法中保留了空实现。

接下来程序初始化 Pygame，创建一个窗口，加载 10 张卡牌图片，并将它们添加到一个 Pygame 精灵组中。程序进入主循环，监听 Pygame 事件，如果点击了鼠标，则检查是否点击了卡牌，如果点击了，则进行翻牌操作。程序在循环中更新精灵组并在屏幕上绘制，最后使用 Pygame.display.update() 更新屏幕显示，并使用 Pygame.time.Clock() 控制帧率。
