利用Python绘制七段数码管（适合初学者）

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
def drawgap():
    t.penup()
    t.fd(5)
#绘制单段数码管   
def drawline(draw):
    t.pendown() if draw else t.penup()
    t.fd(40)
    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)
    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)
    t.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)
    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('月',font = ("Arial",18,"normal"))
            t.pencolor("yellow")
            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

运行结果：
