Thank you very much! That was very useful.

This is not a cygwin or python problem as far as I can tell.
I did the same experiment with SAGE and with the version of python
from the sage 2.0 build. I got very similar results:

BTW I don't mean that any of you would need to create the code for the

a place to run it and I can not use the web host that I will use for

My idea is to have an API system like Google does for search, maps,

I'm surprised that it would suck to say to sage: copy cell(2) of
worksheet(graphics) to worksheet( Christian) or copy all of "graphics"
to " Christian".
Is there going to be a template system so that students in a class all
start out with the same worksheet that the teacher created?

Copying cells around would suck for what you're doing, no matter how easy we
could make it. There is also a forthcoming feature in which you will be able
to edit files, similar to the worksheet editing mode, and attach them to your
SAGE session.
