Total Newbie question for which I have searched the site. I am running a really simple program in Chapter 2 of Automate the Boring Stuff and I keep getting a NameError. The first line is

if name == 'Alice':

推荐答案

在 book 中，您错过了此评论在代码上方:(假装名称之前已分配了一些值.)".所以你需要这样做.例如(假设 Python 3):

In the book you missed this comment above the code: "(Pretend name was assigned some value earlier.)". So you need to do that. For example (assuming Python 3):

name = input("Please enter your name: ")
if name == 'Alice':
    print('Hi, Alice.')

顺便说一句，下次您在搜索引擎中搜索此类内容时，请在异常类型前加上python"，例如python NameError".

By the way, next time you are searching for this kind of thing in a search engine, prefix the exception type with "python", for example "python NameError".
