七段数码管（seven-segmentindicator）由7段数码管拼接而成，每段有亮或不亮两种情况，改进型的七段数码管还包括一个小数点位置

绘制模式：

input：输入当前日期的数字形式

process：根据每个数字绘制七段数码管表示

output：绘制当前日期的七段数码管表示

示例一：

#DrawSevenSegDisplay.py 
import turtle, datetime 
def drawLine(draw):  #绘制单段数码管 
  turtle.pendown() if draw else turtle.penup() 
  turtle.fd(40) 
  turtle.right(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.left(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.left(180) 
  turtle.penup() 
  turtle.fd(20) 
def drawDate(date): #获得要输出的数字 
  for i in date: 
    drawDigit(eval(i)) #注意: 通过eval()函数将数字变为整数 
def main(): 
  turtle.setup(800, 350, 200, 200) 
  turtle.penup() 
  turtle.fd(-300) 
  turtle.pensize(5) 
  drawDate(datetime.datetime.now().strftime('%Y%m%d')) 
turtle.hideturtle()
main()
