I am very interested in your use of Axiom in Sage. I was beginning to

I'm having no luck getting the "bins" option to pylab.hist() to work.
Here's an example:
fish_data=[random() for i in range(100)]
import pylab
import numpy
divats = numpy.arange(0.0,1.0,0.1)
pylab.hist(fish_data, bins=divats)
pylab.savefig('sage.png')
Without the "bins=divats" it gives the expe

Hi, I'm trying to run a simple script that basically loops through a
long list of polynomials, does some things with them in Axiom, and
imports the results back to Sage. After running for a while (60-90
minutes) it will hang with the message "Axiom crashed -- automatically

Its not the same issue, but http://trac.sagemath.org/sage_trac/ticket/5206
is somewhat related. I have taken to only using .py files, which seem
more robust in general.

I have a finite dimensional vector space V/k, and various
automorphisms (i.e. members of GL(V)). I would like to construct the
field k(X), where the variables in X correspond to a basis of V, along
with the operation of GL(V) on k(X). Is there some existing way to do
this in SAGE, or do I need t
The very crude solution I use with pure python is to put stuff in the
site-packages directory. In sage, this is in
$SAGE_ROOT/local/lib/python/site-packages. It is where most python
packages install themselves.

I think the most "pythonic" solution would be to use
itertools.product, which requires python 2.6 or greater (and hence
sage 4.1 or greater):
sage: import itertools
sage: for x,y in iter
I know that you can modify sys.path which is where python looks to
find where to use import. The question that I should have asked is
how does one develop new sage functions. It makes sense for each
project to have its own directory to contain the pieces of stuff.
What I'd like is to have some s
Hi Victor. Although I don't know the answer to your question, I'm
sure that it actually a python question (rather than a sage one) so I
expect that the answer lies somewhere in the wealth of online python
documentation!
Of course someone else might give a more helpful answer...

I have a sage program in a file in one of my directories called
calc.sage. It uses a class that I wrote called Table, which I've put
in a file called Table.py in the same directory. In the sage notebook
I load calc.sage (by explicitly giving the path to the directory), and
calc.sage has a line

while 2^x*3^y != 12 and y < 10:
y = y + 1

One way is to use an exception:
class GetOut(Exception): pass
try:
for x in range(10):
for y in range(10):
if 2^x*3^y==12:
raise Get

I would like that :
def foo():
for x in range(10):
for y in range(10):
if 2^x*3^y==12:
return (x,y)
The return command exits
How does one break from a double for loop, or a loop of two variables?
for example:
for x in range(10):
for y in range(10):
if 2^x*3^y==12:
break
(x,y)
I want this to return (2,1) rather than (9,1). This is just a
simplified example, but that is the approxima
I'm not sure if or when either of these will be available, but
neither are trivial. Both questions are probably better asked on the

It's not so much that I haven't read the documentation, but rather
that the definitions have been unclear.
It's not Sage, it's me--things have been unclear all my life. To
paraphrase from 1969's "Both sides now", I really don't know
"numerical_eigenforms" at all. What Sage calls a cusp form on
