[已解决]在学习while循环语句时为什么不能按照下列逻辑呢？

monsterlou

print('Hello World')
temp = input('can you input the right number i\'m thinking: ')
guess = int(temp)
if guess == 8:
        print('Yes you\'re right!')
        print('we have no gift for you')
else:
        while guess != 8:
            temp = input('Take one more try: ')
            guess = int(temp)
            if guess < 8:
                print('Nope guess bigger one')
            else:
                print('maybe little one!')
print('Game Over')

新入门菜鸟，有诸多不理解的地方，请大神赐教这段代码有什么问题？
为什么结果是这样？
Hello World
can you input the right number i'm thinking: 9
Take one more try: 12
maybe little one!
Take one more try: 13
maybe little one!
Take one more try: 5
Nope guess bigger one
Take one more try: 4
Nope guess bigger one
Take one more try: 3
Nope guess bigger one
Take one more try: 3
Nope guess bigger one
Take one more try: 8
maybe little one!
Game Over

因为你的程序逻辑不对啊。if else中没有判断guess等于8的情况啊。

1. temp = input('can you input the right number i\'m thinking: ')
   
2. guess = int(temp)
   
3. if guess == 8:
   
4.         print('Yes you\'re right!')
   
5.         print('we have no gift for you')
   
6. else:
   
7.         while guess != 8:
   
8.             temp = input('Take one more try: ')
   
9.             guess = int(temp)
   
10.             if guess < 8:
    
11.                 print('Nope guess bigger one')
    
12.             elif guess > 8:
    
13.                 print('maybe little one!')
    
14.             else:
    
15.                 print('Yes you\'re right!')
    
16.                 print('we have no gift for you')
    
17. print('Game Over')

若你认为进入while循环后就不该在判断guess等于8的情况，那么程序应该这样修改：

1. temp = input('can you input the right number i\'m thinking: ')
   
2. guess = int(temp)
   
3. if guess == 8:
   
4.         print('Yes you\'re right!')
   
5.         print('we have no gift for you')
   
6. else:
   
7.         while guess != 8:
   
8.             if guess < 8:
   
9.                 print('Nope guess bigger one')
   
10.             else:
    
11.                 print('maybe little one!')
    
12.             temp = input('Take one more try: ')
    
13.             guess = int(temp)
    
14. print('Game Over')

        while 本该是总览全局的角色，而在楼主的代码中却只能偏居一隅，实在是“桌子底下放风筝”啊！

1. print('Hello World')
   
2. guess = 0
   
3. while guess != 8:
   
4.     guess = int(input('can you input the right number i\'m thinking: '))
   
5.     if guess == 8:
   
6.         print('Yes you\'re right!')
   
7.         print('we have no gift for you')
   
8.     else:
   
9.         print('Take one more try: ')
   
10.         if guess < 8:
    
11.             print('Nope guess bigger one')
    
12.         else:
    
13.             print('maybe little one!')
    
14. print('Game Over')
