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("迴圈執行完啦")
9 print("-----out of while loop ------")

結果:

Loop 1
Loop 2
Loop 3
Loop 4
Loop 5
Loop 6
迴圈執行完啦
-----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("迴圈執行完啦")
9 print("-----out of while loop ------")

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

結論：while迴圈正常執行完不會執行else裡邊的代碼，如果while迴圈被break中斷則會執行else裡邊的代碼
