7段数码管绘制python实验

实验代码如下：

 1 import turtle, time
 2 def drawGap():
 3     turtle.penup()
 4     turtle.fd(5)
 5 def drawLine(draw):      #绘制单段数码管
 6     drawGap()
 7     turtle.pendown() if draw else turtle.penup()    #如果draw为真值则画，如果不是则抬起画笔移动
 8     turtle.fd(40)     #向该方向行进40像素
 9     drawGap()
10     turtle.right(90)  #转向90度
11 def drawDigit(digit):    #根据数字绘制七段数码管
12     drawLine(True) if digit in [2,3,4,5,6,8,9] else drawLine(False)
13     drawLine(True) if digit in [0,1,3,4,5,6,7,8,9] else drawLine(False)
14     drawLine(True) if digit in [0,2,3,5,6,8,9] else drawLine(False)
15     drawLine(True) if digit in [0,2,6,8] else drawLine(False)
16     turtle.left(90)
17     drawLine(True) if digit in [0,4,5,6,8,9] else drawLine(False)
18     drawLine(True) if digit in [0,2,3,5,6,7,8,9] else drawLine(False)
19     drawLine(True) if digit in [0,1,2,3,4,7,8,9] else drawLine(False)
20     turtle.left(180)
21     turtle.penup()    #为绘制后续数字确定位置
22     turtle.fd(20)     #...
23 def drawDate(date):   #获得要输出的数字，日期格式为：'%Y-%m=%d+'
24     turtle.pencolor("red")
25     for i in date:
26         if i == '-':
27             turtle.write('年',font=("Arial",18,"normal"))
28             turtle.pencolor("green")
29             turtle.fd(40)
30         elif i == '=':
31             turtle.write('月',font=("Arial",18,"normal"))
32             turtle.pencolor("blue")
33             turtle.fd(40)
34         elif i == '+':
35             turtle.write('日',font=("Arial",18,"normal"))
36         else:
37             drawDigit(eval(i))   #通过eval()函数将数字变为整数
38 def main():
39     turtle.setup(800, 350, 200, 200)     #设置画布大小
40     turtle.penup()        
41     turtle.fd(-300)      #当前画笔初始绘制所在位置
42     turtle.pensize(5)
43     drawDate(time.strftime('%Y-%m=%d+',time.gmtime()))   #调用函数
44     turtle.hideturtle()
45     turtle.done()
46 main()

运行结果如下：
