First time users are strongly advised to read the Getting started guide which explains how to properly configure PyDev.


The recommended way of using PyDev is bundled in LiClipse, which provides PyDev builtin as well as support for other languages such as Django Templates, Mako, RST, C++, CoffeScript, Dart, HTML, JavaScript, CSS, among others (also, by licensing LiClipse you directly support the development of PyDev).
