Install PyDev for Python as an Eclipse Plugin
PyDev enables Eclipse to support Python (and is among the leading tools for Python coding). It's also an open source project created by Aleks Totic in 2003 and kept going by Fabio Zadrozny since 2005.
PyDev is a third-party plug-in for Eclipse. It is an Integrated Development Environment (IDE) used for programming in Python supporting code refactoring, graphical debugging, code analysis among other features.
Until September 2009, two versions of PyDev existed: an open source version, and a shareware version called PyDev Extensions. Certain advanced features such as code analysis, quick-fixes, and remote debugging were reserved for the non-free version. On September 3, 2009, Aptana announced PyDev version 1.5, a combined version of PyDev and PyDev Extensions, all available under the Eclipse Public License.
