绘制奥运五环标记

源码：

#绘制奥运五环

import turtle

turtle.width(10)

turtle.color("blue")

turtle.circle(50)

turtle.penup()

turtle.goto(120,0)

turtle.pendown()

turtle.color("black")

turtle.circle(50)

turtle.penup()

turtle.goto(240,0)

turtle.pendown()

turtle.color("red")

turtle.circle(50)

turtle.penup()

turtle.goto(60,-50)

turtle.pendown()

turtle.color("yellow")

turtle.circle(50)

turtle.penup()

turtle.goto(180,-50)

turtle.pendown()

turtle.color("green")

turtle.circle(50)

本章实操作业

1. 建立 Python 开发环境，并完成第一个 Python 程序。将整个过程使用图文描述出来。

2. 根据老师代码，完成奥运五环的绘图程序

3. 使用海龟绘图，输出四个矩形：

源码：

#使用海龟绘图绘制4个矩形

import turtle

turtle.showturtle() #显示箭头

#绘制4个阴影

turtle.width(4)

turtle.color("#e9e7ef") #颜色查编程颜色代码，html的颜色代码通用

turtle.penup()

turtle.goto(5,-5)

turtle.pendown()

turtle.forward(100)

turtle.left(90) #箭头左转90度

turtle.forward(100)

turtle.left(90)

turtle.forward(100)

turtle.left(90)

turtle.forward(100)

turtle.left(90)

turtle.penup()

turtle.goto(135,-5)

turtle.pendown()

turtle.forward(100)

turtle.left(90) #箭头左转90度

turtle.forward(100)

turtle.left(90)

turtle.forward(100)

turtle.left(90)

turtle.forward(100)

turtle.left(90)

turtle.penup()

turtle.goto(5,-145)

turtle.pendown()

turtle.forward(100)
