In python all is clear, you write a .py file and supply the docstring with proper reST text and code for epydoc, doctest and/or Sphinx. With nzmath you can do a lot of math things (and it works also on my phone :-) Why is the above senence about nzmath here? It seems like a subliminal message. I removed some sentences before this one, but this one remained It hasn't anything to do with the actual question. Sage uses .sage files and worksheets, and the way to document is described in the development manual. You can also just write Python code (with a .py extension) and put import sage.all at the top of your file, then use Sage functions via "sage.all". Then everything is just like you describe with Python above. Well, not quite actually. The manual says define a SAGE_ROOT, but that's not enough also. I found http://wiki.sagemath.org/Sage_in_systemwide_python , but that example also gives an error. When I added an environment variable SAGE_DOC (the error was complaining about not finding it) it worked (using the LD_LIBRARY_PATH line). thanks, Ton Biegstraaten --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

[sage-support] Re: Upgrading Sage Notebook
And a follow on: I am regularly coming up against the problem of having some cookie which results in an error page when I go to Sage. I have to delete all cookies for my server to correct this. Is there some way to avoid this situation? I thought it was my upgrade that was causing the problems (incompatible worksheets), hence the desire to start from scratch and move the user DB and worksheets over. It looks like the real cause of the problem was this cookie situation.

[sage-support] Using sage code from within Python
Hi,
In the following code a.taylor works both when using load and starting
it with python, b.taylor works with load within sage but gives the
exception when using python. There is no difference when using the
python version from the sage tree.
I removed superfluous python code. The code is the generating function
for a unordered partition.
---
# be sure sage can be found when using Python
# comment it when starting from within sage with load
from sagePaths import *
set_paths()
#
from sage.all import *
from operator import *
if __name__ == __main__:
var('x')
a = prod([1/(1-x**i) for i in range(1, 8)])
b = prod([1/(1-x**i) for i in range(1, 9)])
print a.taylor(x,0,5)
print b.taylor(x,0,5)
Result when using python:
54 32
