1.太阳花

import turtleimport time

turtle.speed(10)#同时设置pencolor=color1, fillcolor=color2
turtle.color("red","yellow")
 
turtle.begin_fill()for _inrange(50):
    turtle.forward(200)
    turtle.left(170)
turtle.end_fill()
turtle.done()

2.螺旋方阵

import turtle
turtle.color('red','yellow')
turtle.speed("fastest")
turtle.begin_fill()for xinrange(100):
     turtle.forward(2*x)
     turtle.left(90)
turtle.end_fill()
turtle.done()

3.彩色螺旋

import turtle
turtle.speed("fastest")
turtle.pensize(2)
turtle.bgcolor("black")
colors=["red","blue","yellow","purple"]for xinrange(300):
    turtle.color(colors[x%4])
    turtle.forward(2*x)
    turtle.left(91)
turtle.done()

import turtle
turtle.speed("fastest")
turtle.pensize(2)
turtle.bgcolor("black")
turtle.color("red")for x inrange(200):
    turtle.forward(x)
    turtle.left(61)
turtle.done()

要是想超快的绘制，把turtle.speed("fastest")换成turtle.tracer(0)，打开直接就是结果。

4.七段数码管

import turtle,timedefdrawLine(draw):
    turtle.pendown()if drawelse turtle.penup()
    turtle.fd(40)
    turtle.right(90)defdrawDight(dight):#根据数字绘制七段数码管
    drawLine(True)if dightin[2,3,4,5,6,8,9]else drawLine(False)
    drawLine(True)if dightin[0,1,3,4,5,6,7,8,9]else drawLine(False)

    drawLine(True)if dightin[0,2,6,8]else drawLine(False)
    turtle.left(90)
    drawLine(True)if dightin[0,4,5,6,8,9]else drawLine(False)
    drawLine(True)if dightin[0,2,3,5,6,7,8,9]else drawLine(False)
    drawLine(True)if dightin[0,1,2,3,4,7,8,9]else drawLine(False)
    turtle.left(180)
    turtle.penup()#为绘制后续数字确定位置
    turtle.fd(20)#为绘制后续数字确定位置defdrawDate(date):
    turtle.pencolor("red")for iin date:if i=='-':
            turtle.write('年',font=("Arial",18,"normal"))
            turtle.pencolor("green")
            turtle.fd(40)elif i=='=':
            turtle.write('月',font=("Arial",18,"normal"))
            turtle.pencolor("blue")
            turtle.fd(40)elif i=='+':
            turtle.write('日',font=("Arial",18,"normal"))else:
            drawDight(eval(i))defmain():
    turtle.speed(10)
    turtle.setup(800,350,200,200)
    turtle.penup()
    turtle.fd(-300)
    turtle.pensize(5)
    drawDate(time.strftime('%Y-%m=%d+',time.gmtime()))
    turtle.hideturtle()
    turtle.done()
main()

1.打开方法

turtledemo 包汇集了一组演示脚本。在cmd命令行中打入
