Python运行提示错误need more than 1 value to unpack

在练习ex14中，
运行提示错误need more than 1 value to unpack

才发现再一次，又忘了同时Python ex14.py 的时候应该加上另外一个参数。
代码：
————————————————————————————
from sys import argv

script, user_name = 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)

在一开始定义了两个参数，一个script也就是运行时候的ex14.py也就是文件名本身。另一个参数是user_name，因此在Windows Powershell运行的时候Python ex14.py Zad
即可。
