Python while loop with user input
提问by leela.fry
I have this simple little program which doesn't work. I want the program to keep asking the user for my name till they guess it.
我有这个简单的小程序，它不起作用。我希望程序不断向用户询问我的名字，直到他们猜到为止。
The program throws an error message after the first attempt. I can't work it out where the problem is.
第一次尝试后，程序会抛出错误消息。我无法弄清楚问题出在哪里。
name = "not_aneta"
while name != "aneta":
name = input("What is my name? ")
if name == "aneta":
print "You guessed my name!"
When I run it I get an error message:
当我运行它时，我收到一条错误消息：
Traceback (most recent call last):
File "C:\Users\Aneta\Desktop\guess_my_name.py", line 4, in <module>
name = input("What is my name? ")
File "<string>", line 1, in <module>
NameError: name 'aneta' is not defined

You have to use raw_input(inputtries to run the input as a python expression and this is not what you want) and fix the indentation problem.
您必须使用raw_input(input尝试将输入作为 python 表达式运行，这不是您想要的) 并修复缩进问题。
name = "not_aneta"
while name!= "aneta":
name = raw_input("What is my name? ")
if name == "aneta":
print "You guessed my name!"

It seems that your are using 2.x so you need raw_inputfor strings.
似乎您使用的是 2.x，因此您需要raw_input字符串。
name = "not_aneta"
while name!= "aneta":
name = raw_input("What is my name? ")
also, the ifstatements is pretty pointless because the program won't continue until the user guesses the correct name. So you could just do:
此外，这些if语句也毫无意义，因为在用户猜出正确名称之前，程序不会继续运行。所以你可以这样做：
name = "not_aneta"
while name!= "aneta":
name = raw_input("What is my name? ")
print "You guessed my name!"
