1、逢7跳过小游戏：从1-100之间，遇到带7的数字或者7的倍数跳过。

1 for i in range(1,101):
2     if i == 7 or i % 10 == 7 or i // 10 == 7:
3         continue
4     else:
5         print(i,end = "，")

2、七段数码管的绘制：模拟电子管显示屏显示日期

 1 import turtle
 2 import time
 3 def drawGap():
 4     turtle.penup()
 5     turtle.fd(5)
 6 def drawLine(draw):
 7     drawGap()
 8     turtle.pendown() if draw else turtle.penup()
 9     turtle.fd(40)
10     drawGap()
11     turtle.right(90)
12 #开始绘制
13 def drawDigit(digit):
14     drawLine(True) if digit in (2,3,4,5,6,8,9) else drawLine(False)
15     drawLine(True) if digit in (0,1,3,4,5,6,7,8,9) else drawLine(False)
16     drawLine(True) if digit in (0,2,3,5,6,8,9) else drawLine(False)
17     drawLine(True) if digit in (0,2,6,8,9) else drawLine(False)
18     turtle.left(90)
19     drawLine(True) if digit in (0,4,5,6,8,9) else drawLine(False)
20     drawLine(True) if digit in (0,2,3,4,5,6,7,8,9) else drawLine(False)
21     drawLine(True) if digit in (0,1,2,3,4,7,8,9) else drawLine(False)
22     turtle.left(180)
23     turtle.penup()
24     turtle.fd(20)
25 def drawDate(date):
26     turtle.pencolor("red")
27     for i in date:
28         if i == "-":
29             turtle.write(‘年‘,font=("Arial",18,"normal"))
30             turtle.pencolor("green")
31             turtle.fd(40)
32         elif i == "=":
33             turtle.write(‘月‘,font=("Arial",18,"normal"))
34             turtle.pencolor("green")
35             turtle.fd(40)
36         elif i == "+":
37             turtle.write(‘日‘,font=("Arial",18,"normal"))
38         else:
39             drawDigit(eval(i))
40 def main():
41     turtle.setup(800,350,200,200)
42     turtle.penup()
43     turtle.fd(-300)
44     turtle.pensize(5)
45     drawDate(time.strftime(‘%Y-%m=%d+‘,time.gmtime()))
46     turtle.hideturtle()
47     turtle.done()
48 main()
