Download latest python from http://www.python.org/download/releases
Download Eclipse from http://www.eclipse.org/downloads/ . Any of the eclipse will work. But I recommend to download the classic eclipse.
For Eclipse you need to have java installed in your machine. Windows doesn’t comes with java by default.
First install python. Just double click and follow the instructions. You may stick to the default configurations.
Then install eclipse. Extract the zip file. You may copy the entire eclipse folder to ProgramFiles or simply run eclipse from anywhere you want.
This is not the end. We need further process.
We need to install Pydev. That’s the development environment for python. Or you can say it’s the necessary plugin to configure eclipse for running python.
