What is PyDev?

PyDev is a Python IDE for Eclipse, which may be used in Python, Jython and IronPython development.

It comes with many goodies such as:

For more details on the provided features, check the Features Matrix.


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).

    • Minimap is enabled by default.
    • The minimap now shows content based on the outline.
    • It's possible to customize the minimap selection color.
