Python【从入门到精通】_图形化程序设计（奥运五环）

首次绘图

>>> import turtle #导入 turtle 模块
>>> turtle.showturtle() #显示箭头
>>> turtle.write("攻城狮") #写字符串
>>> turtle.forward(300) #前进 300 像素
>>> turtle.color("red") #画笔颜色改为 red
>>> turtle.left(90) #箭头左转 90 度
>>> turtle.forward(300)
>>> turtle.goto(0,50) #去坐标（0,50）
>>> turtle.goto(0,0)
>>> turtle.penup() #抬笔。这样，路径就不会画出来
>>> turtle.goto(0,300)
>>> turtle.pendown() #下笔。这样，路径就会画出来
>>> turtle.circle(100) #画圆

绘制奥运五环标记

import turtle
turtle.width(10)
turtle.color("blue")
turtle.circle(50)
turtle.color("black")
turtle.penup()
turtle.goto(120,0)
turtle.pendown()
turtle.circle(50)
turtle.color("red")
turtle.penup()
turtle.goto(240,0)
turtle.pendown()
turtle.circle(50)
turtle.color("yellow")
turtle.penup()
turtle.goto(60,-50)
turtle.pendown()
turtle.circle(50)
turtle.color("green")
turtle.penup()
turtle.goto(180,-50)
turtle.pendown()
turtle.circle(50)
