While循环替换Else语句？（Python）的

Question

确定这里是

done = False 
    while not done: 
     quit = input ("Do you want to quit? ") 
     if quit == "y" : 
     done = True; 

     if not done: 
     attack = input ("Does your elf attack the dragon? ") 
     if attack == "y": 
      print ("Bad choice, you died.") 
      done = True; 

，但是当我到达

  Do you want to quit? 

我进入

 n 

我得到

 Traceback (most recent call last): 
     File "C:\Users\your pc\Desktop\JQuery\dragon.py", line 4, in <module> 
      quit = input ("Do you want to quit? ") 
     File "<string>", line 1, in <module> 
     NameError: name 'n' is not defined 

根据此http://www.youtube.com/watch?feature=player_embedded&v=2Z2pH0Ls9Ew#！ 它应该工作

Answer 1

input在Python的版本2和3中表现不同。你很清楚Python 2，因为它试图解释Python环境中的输入。

您只需要raw_input()即可读取字符串。

编辑： 为了使差明确，在Python 2：

>>> type(input()) 
0 
<type 'int'> 
>>> type(raw_input()) 
0 
<type 'str'> 

在Python 3：

>>> type(input()) 
0 
<class 'str'>
