Course Information

Assignment 1: Get really started with Python

Due September 8 at 12:3o pm (before class)


Create a file named with the following convention:

LastNameFirstName_assignment1.py

This is the main file where all your code will reside.
•We will evaluate each question/sub-question as:
 

>>> python LastNameFirstName_assignment1.py question1

>>> python LastNameFirstName_assignment1.py question1.1
 

(For the few non programming questions, create a string with your answer and print it)

•Add logic to your code based on the command line argument (process your command line argument string ) and output accordingly. The command line arguments in python are accessed through sys.argv list .  You can also use getopt module.
 
Make sure you  include a this header information in the beginning of your code
 

#! /usr/bin/env python  

#author: ‘Your name'
#email = ‘your email address'
#python_version = ‘python version you are using'
