[YLUG] Spreadsheets in Python?

[Simon Ward]

A question for the Pythonistas present:

A work-related project that I'm working on demands some kind of 
spreadsheet functionality so that users can input/modify data in a 
relatively painless manner. We have an ad-hoc solution in place right 
now but for large datasets it's mind-buggeringly slow.

We're toying with the idea of using Gnumeric for data modification etc., 
with an instance of Gnumeric being fork()'d when the user wishes to 
modify data, but it contains a whole load of additional fluff that we 
just don't need (Excel compatibility is handy, though), and that's 
before we get into the nightmare that is building anything GNOME related.

Does anyone know of any spreadsheet applications (or even spreadsheet 
classes) written in Python? We don't need anything fancy - the ability 
to load, save and modify CSV data is sufficient (plotting of datasets 
would be nice, but we have modules that can do that if required), and a 
Tkinter-type interface would be handy. I'm aware that Gnumeric can speak 
Python, but it appears that a lot of the functionality is only available 
from within  Gnumeric itself.

We've already discounted using the NovaGrid spreadsheet widget because 
it flatly refuses to work with Python 2.4

Any suggestions?
