Writing your first Python program may feel daunting - follow me here as I show you how to start a simple program inside PyDev (you could write this in any editor). I cover the useful features of PyDev including tooltips, auto-completion and using a 'Extract Method' refactoring tool (great for cleaning up your code!).

This simple script will read a list of numbers from a text file (as strings) and convert these to integers. We create a simple text file of numbers and process them using a Python loop, storing the converted integers in an array. This demonstrates simple looping and data processing techniques which will be useful if you need to process your own data.

The source code and data file (numbers.py, nbrs.txt) are available in the wiki so you can cut/paste them onto your own system. Now come join me in the forum for questions and tasks.
