**代码：**

import turtle #引入绘图库turtle
    def drawLine(draw):   #绘制单段数码管
        turtle.pendown() if draw else turtle.penup()
        turtle.fd(40) #前进40像素
        turtle.right(90)#旋转90度，完成一条线的绘制
    def drawDight(dight):#根据数字绘制七段数码管
        drawLine(True) if dight in [2,3,4,5,6,8,9] else drawLine(False)
        drawLine(True) if dight in [0,1,3,4,5,6,7,8,9] else drawLine(False)
        drawLine(True) if dight in [0,2,3,5,6,8,9] else drawLine(False)
        drawLine(True) if dight in [0,2,6,8] else drawLine(False)
        turtle.left(90)
        drawLine(True) if dight in [0,4,5,6,8,9] else drawLine(False)
        drawLine(True) if dight in [0,2,3,5,6,7,8,9] else drawLine(False)
        drawLine(True) if dight in [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
    def drawDate (date):#获得要输出的数字
        for i in date:
            drawDight(eval(i))  #通过eval()函数家将数字转化为整数
            
    def main():
        turtle.setup(800,350,200,200)
        turtle.penup()
        turtle.fd(-300)
        turtle.pensize(5)
        drawDate('20200217')
        turtle.hideturtle()
        turtle.done()
    main()
