IDLE - Integrated DeveLopment Environment
An IDE is an Integrated Development Environment.
It provides a collection of all the tools needed to create a program.
IDLE is an IDE for creating Python programs (named after Eric Idle.)
Documentation for IDLE can be found in the Python 2.6 documentation but ...
... basic operation is quite easy so there is no need to use the documentation yet.
On a Microsoft Windows PC, start IDLE by:
Start > Programs > Python 2.6 > IDLE (Python GUI)
By default, a Python Shell window will be displayed.
