Answer / chaitu

heloothere.py file

#!/usr/bin/env python

# import modules used here -- sys is a very standard one

import sys

# Gather our code in a main() function

def main():

print 'Hello', sys.argv[1]

# Command line args are in sys.argv[1], sys.argv[2] ...

# sys.argv[0] is the script name itself and can be ignored

# Standard boilerplate to call the main() function to begin

# the program.

if __name__ == '__main__':

main()

$ python hello.py User
