python turtle库的几个小demo，,一、先上图一个同切圆

一、先上图

一个同切圆和五角星

上代码

import turtle#同切圆turtle.pensize(2)turtle.circle(10)turtle.circle(40)turtle.circle(80)turtle.circle(160)#五角星from turtle import *color(‘red‘,‘yellow‘)begin_fill()for i in range(5):    fd(200)    rt(144)end_fill()done()

　　三、七段数码管日期显示

#七段数码管绘制import turtleimport timedef drawGap(): #控制数码管间隔    turtle.penup()    turtle.fd(5)def drawLine(draw):#绘制单段数码管    drawGap()    turtle.pendown() if draw else turtle.penup()    turtle.fd(40)    drawGap()    turtle.rt(90)def drawDigit(digit):#根据数字绘制七段数码管    drawLine(True) if digit in [2,3,4,5,6,8,9] else drawLine(False)    drawLine(True) if digit in  [0,1,3,4,5,6,7,8,9] else drawLine(False)    drawLine(True) if digit in  [0,2,3,5,6,8,9] else drawLine(False)    drawLine(True) if digit in [0,2,6,8] else drawLine(False)    turtle.lt(90)    drawLine(True) if digit in  [0,4,5,6,8,9] else drawLine(False)    drawLine(True) if digit in  [0,2,3,5,6,7,8,9] else drawLine(False)    drawLine(True) if digit in  [0,1,2,3,4,7,8,9] else drawLine(False)    turtle.lt(180)    turtle.penup()    turtle.fd(20)def drawDate(date): #获得需要输出的数字 %Y-%m=%d+    turtle.pencolor(‘red‘)    for i in date:        if i==‘-‘:            turtle.write(‘年‘,font=(‘Arial‘,24,‘normal‘))            turtle.pencolor(‘yellow‘)            turtle.fd(40)        elif i==‘=‘:            turtle.write(‘月‘,font=(‘Arial‘,24,‘normal‘))            turtle.pencolor(‘green‘)            turtle.fd(40)        elif i==‘+‘:            turtle.write(‘日‘,font=(‘Arial‘,24,‘normal‘))        else:            drawDigit(eval(i))def main():    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()

　　以上三个小demo，都是用turtle库绘制完成的，turtle绘制方面，只有你想不到，没有他做不到的。
