Python中的画图初体验

学到《父与子编程之旅》的16章了，跟书上的例子进行学习，学会了画圆，我又找到了画线的方法，于是就可以在screen上画日本国旗了：

手动画的不好看，也可以不手动画，直接画线：

代码如下：

 1 import pygame,sys
 2 from pygame.locals import *
 3 print pygame.ver
 4 pygame.init()
 5 screen = pygame.display.set_mode([640,480])
 6 color=(200,156,64)
 7 points=[]
 8 screen.fill([255,255,255])
 9 pygame.draw.circle(screen,[255,0,0],[200,200],70,0)
10 pygame.draw.line(screen,color,(20,20),(400,20),1)
11 pygame.draw.line(screen,color,(20,20),(20,400),1)
12 pygame.draw.line(screen,color,(20,400),(400,400),1)
13 pygame.draw.line(screen,color,(400,400),(400,20),1)
14 pygame.display.flip()
15 running = True
16 while running:
17     for event in pygame.event.get():
18         if event.type == pygame.QUIT:
19             running = False
20 ##        if event.type==MOUSEBUTTONDOWN:
21 ##            points.append(event.pos)
22 ##    if len(points)>1:
23 ##        pygame.draw.lines(screen,color, False, points, 5)
24 ##    pygame.display.update()
25 pygame.quit()
