这几天在学《笨方法学python》，里面的习题14代码如下：
from sys import agrv
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 quertions."
print "do you like me %s?"%user_name
likes = raw_input(prompot)
print "where di 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)
为什么我运行的时候会报错 cannot import name agrv
意思是从sys里面无法调用argv吗？为什么会出现这种情况？
谢谢！
