passing arguments to functions in python using argv

Question

Please find the below script

from sys import argv
script, contact_name, contact_no = argv

def operation()
    some code goes here

Since i run this script from command line, How do i pass contact_name and contact_no to operation function? I am using python 2.7

Answer 1

Command line arguments are passed as an array to the program, with the first being usually the program's location. So we skip argv[0] and move on to the other arguments.

This example doesn't include error checking.

from sys import argv

def operation(name, number):
    ...

contact_name = argv[1]
contact_no = argv[2]

operation(contact_name, contact_no)

Calling from command line:
