Is there a python REPL for Google App Engine?

The Clojure/Compojure people have a drop in repl for Google App Engine, do Python people have anything similar? I use the repl quite a bit in "vanilla" python development, and it would be really useful if I could use it in Google App Engine Python as well.

I have seen the 开发者_如何转开发following http://shell.appspot.com/ demo, and I was basically hoping there might be a drop-in replacement for any Python App Engine project that gave me a repl; even if the repl only worked against the dev server. Anyone know of such a thing?

here is the source code to this demo, just for completeness.

If you're okay with a REPL that works on the dev server, take a look at the bin/python script that Tipfy creates for you. It just loads the Python REPL with your project and the GAE SDK code. I've pasted my version of it here - YMMV, but you can use it as a starting point.
