Spyder

Spyder is a Python development environment with advanced editing, interactive testing, debugging and introspection features. It is especially recommended for scientific computing thanks to NumPy (linear algebra), SciPy (signal and image processing), matplotlib (interactive 2D/3D plotting) and MayaVi’s mlab (interactive 3D visualization) support.

Spyder may also be used as an extension library providing powerful console-related PyQt4 widgets. Spyder is part of spyderlib, a Python module based on PyQt4 and QScintilla2.
