import turtle
import os
turtle.width(10) #设置线条粗细
turtle.penup()
turtle.backward(140)
turtle.pendown()
turtle.color('blue')
turtle.circle(50)
turtle.penup()
# turtle.goto(0,0)
turtle.forward(120)
turtle.pendown()
turtle.color('black')
turtle.circle(50)
#
turtle.penup()
# turtle.goto(240,0)
turtle.forward(120)
turtle.pendown()

turtle.circle(50)
#
turtle.penup()
turtle.goto(-80,-50)
turtle.pendown()
#
turtle.color('yellow')
turtle.circle(50)
#
turtle.penup()
turtle.goto(40,-50)
turtle.pendown()
turtle.color('green')
turtle.circle(50)
#退出窗口的解决办法
# os.system('pause')
# turtle.exitonclick() #等待用户点击界面才退出
# turtle.mainloop() #该句后面的所有代码都无法执行
turtle.done() #功能和mainloop差不多
结果如图所示：
