I've switched to Enthought's Canopy 1.0.0 but I miss the standalone QT shell and the QT notebook. I don't want to use the built-in shell which comes in the IDE. Where can I find the QT shell?
Are you asking about the IPython QtConsole? It and the Ipython notebook (NB this is not a QT notebook; it runs in a browser) are both accessible from the terminal / command prompt:
ipython qtconsole
ipython notebook
But you must have Canopy User Python on your PATH, as described here.
FWIW, the Python shell in Canopy is QtConsole, integrated with the editor and file browser.
