Do you mean something like this: http://magma.maths.usyd.edu.au/calc/ I wrote that like 5 years ago for PARI and Magma, but ended up disabling my versions due to security concerns. > recommend it to my friends - it's great - but something simpler and > faster for quick calculations would also be good, in my opinion) http://sagenb.org is a lot faster during the last 2 weeks than before... But it's definitely not super-simple. > I'm having trouble figuring out everything that's going on with SAGE, > and trying to integrate it into a Python script.

Not that I'm aware of. Maybe somebody else on sage-devel will have some ideas. Personally, I think it would be nearly impossible with a language as flexible as Python. It's better to just run the commands as a very restricted user in a sandboxed virtual machine (like I do with sagenb.org). > > Regards, > Jeff Pickhardt > > PS - Congratulations on your new book. > -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
