while else

1 count = 0
2 while count <= 5 :
3     count += 1
4     if count == 3:pass
5     print("loop",count)
6 
7 else:
8     print("循环执行完啦")
9 print("-----out of while loop ------")

结果:

loop 1
loop 2
loop 3
loop 4
loop 5
loop 6
循环执行完啦
-----out of while loop ------

1 count = 0
2 while count <= 5 :
3     count += 1
4     if count == 3:break
5     print("loop",count)
6 
7 else:
8     print("循环执行完啦")
9 print("-----out of while loop ------")

 

loop 1
loop 2
-----out of while loop ------

结论：while循环正常执行完不会执行else里边的代码，如果while循环被break中断则会执行else里边的代码
