where would we use python argv code example

Example 1: how to take a list as input in python using sys.srgv

#argv in python


import sys

print 'Number of arguments:', len(sys.argv), 'arguments.'
print 'Argument List:', str(sys.argv)

#command in cmd :
$ python test.py arg1 arg2 arg3

# producing following result :
Number of arguments: 4 arguments.
Argument List: ['test.py', 'arg1', 'arg2', 'arg3']
