How to use raw_input with argv?

Question

I am making ex13 from Learn Python The Hard Way

I am 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 am 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 get this error and how to fix it.

Answer 1

You cannot use raw_input()with argv". argvComes with the data that you specify before starting the program. raw_input()Is a Python function, that is, something your program can do. The command line in which you enter the command pythonto start your program is completely separate thing from the program itself.

ScriptName, first, second, third = argv

print "What is your fourth variable?"
fourth = raw_input()
print "What is your fifth variable?"
fifth = raw_input()

argv [] ( ), script.

:

from sys import argv
script, first, second, third = argv # one way to unpack the arguments

script_new = argv[0] # another way
first_new = argv[1]
second_new = argv[2]
third_new = argv[3]

print "original unpacking: ", script, first, second, third
print "argv[] unpacking: ",script_new, first_new, second_new, third_new

argv[0] = raw_input("argument 0? ")
argv[1] = raw_input("argument 1? ")
argv[2] = raw_input("argument 2? ")
argv[3] = raw_input("argument 3? ")

print argv[0], argv[1], argv[2], argv[3]
