rect(Surface,color,Rect,width=0) pygame.draw.rect(screen, BLACK, (50, 50, 150, 50), 0) pygame.draw.rect(sc`reen, BLACK, (250, 50, 150, 50), 1) pygame.draw.rect(screen, BLACK, (450, 50, 150, 50), 10)

这段代码使用了 Pygame 库中的 `draw.rect()` 函数来在屏幕上绘制矩形。该函数的参数包括：

- `Surface`：要绘制矩形的表面对象。
- `color`：矩形的颜色，可以是 RGB 元组或颜色名称常量。
- `Rect`：矩形的位置和大小，以左上角坐标和宽度、高度组成的元组表示。
- `width`：矩形边框的宽度，如果为 0 则表示填充整个矩形。

具体来说，这段代码依次绘制了三个矩形：

- 第一个矩形位于屏幕坐标 (50, 50)，宽度为 150，高度为 50，填充整个矩形，颜色为黑色。
- 第二个矩形位于屏幕坐标 (250, 50)，宽度为 150，高度为 50，边框宽度为 1，颜色为黑色。
- 第三个矩形位于屏幕坐标 (450, 50)，宽度为 150，高度为 50，边框宽度为 10，颜色为黑色。

pygame.quit()

这个代码使用 Pygame 创建了一个简单的画图程序，你可以使用鼠标点击不同的颜色方块，然后在屏幕上绘制出对应颜色的圆形。按下鼠标并拖动可以连续绘制圆形，松开鼠标则停止绘制。按下窗口的关闭按钮可以退出程序。希望对你有帮助！如果还有其他问题，请随时提问。
