How to use raw_input with argv?

Question

I'm doing ex13 from Learn Python The Hard Way

I'm trying to pass:

python ex13.py raw_input() raw_input() raw_input()

my code is below:

from sys import argv

script, first, second, third = argv

print "The script is called:", script
print "Your first variable is:", first
print "Your second variable is:", second
print "Your third variable is:", third

The error I keep getting is:

Traceback (most recent call last):
 File "ex13.py", line 5, in <module>
   script, first, second, third = argv
ValueError: too many values to unpack

I want to know why i'm getting this error and how to fix it

Answer 1

You cannot "use raw_input() with argv". argv is supplied with data that you specify before running the program. raw_input() is a Python function, i.e. something that your program can do. The command line - where you type the python command in order to run your program - is a completely separate thing from the program itself.
