今天根据网上的教程修改了七段数码管的程序，引入了time库函数，这样程序可以
根据系统的时间画出七段数码管了。废话不多说了，直接上程序：
1 #!/usr/bin/env python3
2 # -*- coding: utf-8 -*-
3 #Segement7_2.py
4 import turtle,time
5 def drawGap():
6 turtle.penup()
7 turtle.fd(5)
8 def drawline(draw):
9 drawGap()
10 turtle.pendown() if draw else turtle.penup()
11 turtle.fd(40)
12 drawGap()
13 turtle.right(90)
14 def drawdigit(digit):
15 drawline(True) if digit in [2,3,4,5,6,8,9] else drawline(False)
16 drawline(True) if digit in [0,1,3,4,5,6,7,8,9] else drawline(False)
17 drawline(True) if digit in [0,2,3,5,6,8,9] else drawline(False)
18 drawline(True) if digit in [0,2,6,8] else drawline(False)
19 turtle.left(90)
20 drawline(True) if digit in [0,4,5,6,8,9] else drawline(False)
21 drawline(True) if digit in [0,2,3,5,6,7,8,9] else drawline(False)
22 drawline(True) if digit in [0,1,2,3,4,7,8,9] else drawline(False)
23 turtle.left(180)
24 turtle.penup()
25 turtle.fd(20)
26 def drawdate(date):
27 turtle.pencolor("red")
28 for i in date:
29 if i=='-':
30 turtle.write("年",font=("Arial",18,"normal"))
31 turtle.pencolor("green")
32 turtle.fd(40)

34 turtle.write("月",font=("Arial",18,"normal"))
35 turtle.pencolor("blue")
36 turtle.fd(40)
37 elif i=='+':
38 turtle.write("日",font=("Arial",18,"normal"))
39 else:
40 drawdigit(eval(i))
41 def main():
42 turtle.setup(800,350,200,200)
43 turtle.penup()
44 turtle.fd(-300)
45 turtle.pensize(5)
46 drawdate(time.strftime("%Y-%m=%d+",time.gmtime()))
47 #drawdate('20181010')
48 turtle.hideturtle()
49 turtle.done()
50 main()
