附加题

• 加一个参数进入到代码

# -- coding: utf-8 --

from sys import argv

script, user_name, age = 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 are %d years old.
You live in %r. Not sure where that is.
And you have a %r computer. Nice.
""" % (likes, int(age), lives, computer)

遇到的问题
最后一行，一开始没有用int，报错，说不是数字而是字符，所以就用int将age定义成数字
