绘制多个数码管

#绘制单端数码管
    import turtle
    def drawLine(draw):
        turtle.pendown() if draw else turtle.penup()
        turtle.fd(40)
        turtle.right(90)
    #根据数字绘制七段数码管
    def drawDigit(digit):
        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)
    #获得要输出的数字
    def drawDate(date):
        for i in date:
            drawDigit(eval(i))
    def main():
        turtle.setup(800, 350, 200, 200)
        turtle.penup()
        turtle.fd(-300)
        turtle.pensize(5)       #线条粗细
        turtle.color("red")
        drawDate('20181010')
        turtle.hideturtle()     #使绘制图面不会立即消失
        turtle.done()
    main()						#调用主函数

**运行结果：**

改进：  
1：获取当前系统时间，绘制对应数码管  
2：增加七段数码管之间的间隔线

#七段数码管的绘制
    import turtle as t
    import time

        t.fd(5)

        drawgap()
        t.right(90)
    #根据数值绘制七段数码管 
    def drawdigit(digit):
        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)

        t.left(180)
        t.penup()#为绘制后续数字确定位置
        t.fd(20)#为绘制后续数字确定位置
    #获取日期 
    def drawdate(date):
        t.pencolor("green")
        for i in date:
            if i == '-':
                t.write('年',font = ("Arial",18,"normal"))
                t.pencolor("blue")
                t.fd(40)
            elif i == "=":

                t.write('日',font = ("Arial",18,"normal"))
                t.pencolor("red")
            else:
                drawdigit(eval(i))#通过eval()将数字变成整数
    def main():
        t.setup(800,350,200,200)
        t.penup()
        t.fd(-300)
        t.pensize(5)
        t.color("red")
        drawdate(time.strftime('%Y-%m=%d+', time.gmtime()))#-=+符号分别代表年月日
        t.hideturtle()
        t.done()
    main()#调用main函数
