1.鼠标移动生成彩色圆形

import sys
import pygame
from random import randint

pygame.init()
screen = pygame.display.set_mode((1000,500))
pygame.display.set_caption("666")

pygame.display.flip()
while True:
event = pygame.event.wait()
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
elif event.type == pygame.MOUSEBUTTONDOWN:
mx,my = event.pos
pygame.draw.circle(screen,(255,255,0),(mx,my),50)
pygame.display.update()
elif event.type == pygame.MOUSEMOTION:
mx, my = event.pos
pygame.draw.circle(screen, (randint(0,255),randint(0,255),randint(0,255)),(mx, my), 50)
pygame.display.update()
