for回圈示例：猜數字游戲
1 winning_number = 38 2 for i in range(3): 3 guess_num = int(input("guess num:") ) 4 if guess_num == winning_number : 5 print("yes, you got it. ") 6 break 7 elif guess_num < winning_number: 8 print("think smaller...") 9 else: 10 print("think bigger!") 11 else: 12 print("you have tried too many times..")

1 count = 0 2 while True: 3 print("I love You!!!---%d" %(count)) 4 count += 1 5 if count > 999: 6 break

while回圈升級：根據用戶輸入來決定是否終止游戲
1 winning_number = 38 2 count = 0 3 while count <3: 4 guess_num = int(input("guess num:") ) 5 if guess_num == winning_number : 6 print("yes, you got it.
