Guide to Virtual Environments

A Virtual Environment is a tool to keep the dependencies required by different projects in separate places, by creating virtual Python environments for them. It solves the “Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keeps your global site-packages directory clean and manageable.

For example, you can work on a project which requires Django 1.3 while also maintaining a project which requires Django 1.0.

I highly recommend using virtualenvwrapper, it makes your life so much easier!
