Q-idle is a Qt version of the shell part of the Idle IDE for Python. It runs code in a different process and thus allows easier interruption of the shell (and long running code does not freeze the interface).

• syntax hilighting
• code completion, dict key & filename completion
• doc and function signature tooltips
• reload file on change (just open a file or drag and drop it onto the shell window)
• pretty printing of objects (extensible via plugins) -- pylab.figure, QtGui.QImage, PIL.Image (images, yay :-))

• multiple tabs
• editor
• session saving, history saving
• inspection tools
• debugger
