Now let's get back to programming. There is a tradition that whenever you learn a new programming language, the first program that you write and run is the 'Hello World' program - all it does is just say 'Hello World' when you run it. As Simon Cozens 1 puts it, it is the 'traditional incantation to the programming gods to help you learn the language better' :) .
Start your choice of editor, enter the following program and save it ashelloworld.py#!/usr/bin/python
# Filename : helloworld.py print 'Hello World'
Run this program by opening a shell (Linux terminal or DOS prompt) and entering the command pythonhelloworld.py. If you are using IDLE, use the menu Edit -> Run Script or the keyboard shortcut Ctrl-F5. The output is as shown below.
