PYTHON学习：《笨办法学python》习题14 问题遇见及解决 21/3/30

PYTHON学习：《笨办法学python》习题14，

from sys import argv

script, user_name = argv
prompt = '> '
print ("Hi %r, I'm the %s script." % (user_name, script))
print ("I'd like to ask you a few questions.")
print ("Do you like me %s?" % user_name)
likes = raw_input(prompt)
print ("Where do you live %s?" % user_name)
lives = raw_input(prompt)
print ("What kind of computer do you have?")
computer = raw_input(prompt)
print ("""
Alright, so you said %r about liking me.
You live in %r. Not sure where that is.
And you have a %r computer. Nice.
""" % (likes, lives, computer))

NameError: name 'raw_input' is not defined``

由于在python3中，raw_input已经不用了，所以在python3中是没有定义的。
但是从python2中来说，raw_input的使用范围比input广，可以直接打出字符串，而无需加双引号。

在这里，我用了juypter来写过这篇代码，

from sys import argv
script,user_name =  input(argv)
prompt = '> '
print ("Hi %s, I'm the %s script." %(user_name, script))
print ("I'd like to ask you a few questions.")
print ("Do you like me %s?" %user_name)
likes = raw_input(prompt)
print ("Where do you live %s?" %user_name)
lives = raw_input(prompt)
print ("What kind of computer do you have?")
computer = raw_input(prompt)
print ("""
Alright, so you said %r about liking me.
You live in %r. Not sure where that is.
And you have a %r computer. Nice.
""" %(likes,lives,computer))

希望成为学霸后的我能懂为什么错的。
