分别画出奥运五环和四个矩形

#1.画出奥运五环
import turtle      #导入turtle模块
turtle.width('8')   #设置画线的宽度
turtle.penup()      #抬笔路径，画不出来
turtle.goto(-150,0)  #移动到坐标（-150，0）
turtle.pendown()     #下笔，显示路径
turtle.color('blue')  #显示路径颜色为blue
turtle.circle(50)     #画圆
turtle.penup()
turtle.goto(-30,0)  
turtle.pendown()
turtle.color('black')
turtle.circle(50)
turtle.penup()
turtle.goto(90,0)
turtle.pendown()
turtle.color('red')
turtle.circle(50)
turtle.penup()
turtle.goto(-90,-40)
turtle.pendown()
turtle.color('yellow')
turtle.circle(50)
turtle.penup()
turtle.goto(30,-40)
turtle.pendown()
turtle.color('green')
turtle.circle(50)

2.画出4个矩形

import turtle     #导入turtle模块
#第一个矩形
turtle.color('red')  #设置路径颜色为红色
turtle.penup()
turtle.goto(-100,0)
turtle.pendown()
turtle.forward(50)   #向前移动50
turtle.left(90)      #向左旋转90度
turtle.forward(50)
turtle.left(90)
turtle.forward(50)
turtle.left(90)
turtle.forward(50)

#第二个矩形
turtle.penup()
turtle.goto(-40,50)
turtle.pendown()
turtle.forward(50)
turtle.left(90)
turtle.forward(50)
turtle.left(90)
turtle.forward(50)
turtle.left(90)
turtle.forward(50)

#第三个矩形
turtle.penup()
turtle.goto(-50,-10)
turtle.pendown()
turtle.forward(50)
turtle.left(90)
turtle.forward(50)
turtle.left(90)
turtle.forward(50)
turtle.left(90)
turtle.forward(50)

#第四个矩形
turtle.penup()
turtle.goto(10,-60)
turtle.pendown()
turtle.forward(50)
turtle.left(90)
turtle.forward(50)
turtle.left(90)
turtle.forward(50)
turtle.left(90)
turtle.forward(50)
