x的变式决定了同心圆（关键在r = ball[4]-x）：

import pgzrun #导入游戏库import randomWIDTH = 800#设置窗口宽度HEIGHT = 600#设置窗口高度balls = [] #类似建立一个空文档for i in range(25):x = random.randint(100, WIDTH - 100)y = random.randint(100, HEIGHT - 100)speedx = random.randint(1, 4)speedy = random.randint(1, 4)r = random.randint(5, 50)colorR = random.randint(10, 255)colorG = random.randint(10, 255)colorB = random.randint(10, 255)ball = [x, y, speedx, speedy, r, colorB, colorR, colorG]balls.append(ball)def draw(): #这段是整个框架，之后两段是在里面填充screen.fill('white')for ball in balls: #绘制所有的圆#screen.draw.filled_circle((ball[0],ball[1]),ball[4],(ball[5],ball[6],ball[7]))for x in range(1,ball[4],3):#用同心圆填充screen.draw.filled_circle((ball[0],ball[1]),ball[4]-x,(random.randint(ball[5],255),random.randint(ball[6],255),random.randint(ball[7],255)))def update():# 设置小球自动弹跳for ball in balls:ball[0] = ball[0] + ball[2]ball[1] = ball[1] + ball[3]if ball[0] > WIDTH - r or ball[0] HEIGHT - r or ball[1] < r:ball[3] = - ball[3]pgzrun.go()

鼠标点按的同心圆：
