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
