[sage-support] Re: Number of operands in an expression
That works well, but what about when the expression is multivariate,
such as:
expand((1+x+1/y)^10)
It would be nice to have a general command to count the number of
summands in such an expression.
Yep, I agree. Here is a *terrible* way to do it:
sage: var('x,y')
(x, y)
sage: f = x+y + 1
sage: len(expand(f._maxima_()))
3
sage: len(expand((f**4)._maxima_()))
15
Someone should file an enhancement ticket to do this in a more
sensible way. I also have no idea whether or not it works with
anything more complicated than rational functions -- do you want to
use just rational functions? It might be better to just work with
polynomial rings and their fraction fields ...

Andrew --~--~-~--~-- Andrew (and the others), There is a group of people in my University who would like to integrate in Sage the possibility to produce output in braille maths. It seems that it would be possible to use the braille transcriptor NAT (see: http://natbraille.free.fr or http://liris.cnrs.fr/nat) The main author is Bruno Mascret (he will receive this e-mail, too).

To see that they are actually the same underlying list sage: M[0] is M[1] True To get three copies of the same thing, you can do sage: M = [[0..9] for a in range(3)] sage: M[1].remove(9) sage: print M [[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [0, 1, 2, 3, 4, 5, 6, 7, 8], [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]] Sage tries to avoid this pitfall by making most objects immutable. (An exception is vectors and matrices, where storage considerations make copying expensive, and even they can be made immutable.)

[sage-support] Re: Number of operands in an expression
I think that better way is to use maxima commands op, args, length, atomp I think that for objects which come from Maxima, this is the right thing to do. However, not all symbolic objects in Sage are wrappers for Maxima objects -- in the case of expressions using pynac, the code above actually moves them over to Maxima (via strings and pexpect) and then ask for their length there (which probably ultimately uses the commands you mention). This is less than desirable, hence my claim that it was a terrible way to calculate the length. :) I think a first step might be to introduce a __len__ method for symbolic objects, but then, I'm not always sure what it should return. For instance, what's the length of sin(x^2-y+3)? I could see reasonable arguments for 1 or 4, or maybe even 3. Probably the semantics should be decided by the people who actually use the symbolics a lot, which isn't me ... which is why I haven't filed a trac ticket -- I have no idea what to suggest such a method should do. -cc --~--~-~--~~~---~--~~ 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 -~--~~~~--~~--~--~---

No, the format for multiple edges in a dict of dicts is {u : {v :

[sage-support] The preparser and nested loads
Hi all, I ran into the following unexpected behavior, which I assume is because the preparser does not work with nested loads. I have two files, foo.sage and bar.sage. Their contents are as follows: foo.sage def foo(): return (-1)**(-1) bar.sage load foo.sage The following sage session works as expected: sage: load foo.sage sage: type(foo()) type 'sage.rings.rational.Rational' The following session does not: sage: load bar.sage sage: type(foo()) type 'float' I'm guessing that in the second session the file foo.sage is not getting preparsed (and so foo() returns a Python object and not a Sage object). Is this correct? If so, is there a way to force it to be preparsed? I like to have lots of little files with different functions, and then a file which loads whichever of these happen to be working/relevant at the moment. That way I only have to load one file at the start of my session. Any advice is much appreciated!

for Maxima objects -- in the case of expressions using pynac, the
code above actually moves them over to Maxima (via strings and
pexpect) and then ask for their length there (which probably
ultimately uses the commands you mention). This is less than
desirable, hence my claim that it was a terrible way to calculate
the length. :)
I think a first step might be to introduce a __len__ method for
symbolic objects, but then, I'm not always sure what it should
return.
I would argue that this is a good reason not to implement it :).
Something like nops would be trivial to implement though, and
probably a good idea.
It's in pynac already:
sage: var('x,y',ns=1)
(x, y)
sage: f = expand((1+x+1/y)^10)
sage: f.nargs()
66
I could hook this up to __len__ as well, since __getitem__ lets you
access parts of the expression. E.g.,
sage: f[0]
x^10
sage: f[1]
10*x^9

[sage-support] Re: Number of operands in an expression
Is pynac still being actively developed? From its web pages it seems
not; anyway I would have thought that most of its functionality would
have found a better and better-maintained home in Sage.
Anyway, I've just discovered that all of this can be done using
Maxima:
p=expand((1+x+1/y)^10)
maxima.nterms(p)
All somebody needs to do is to rewrite the lisp code for nterms into
python - and there you go!

I rather focus on the concepts than fighting with my body just inputing code/math symbols etc. Let give a bit more about my background. Since boyhood, I have always noticed and valued visual patterns and grasped and delighted in abstract relationships well but not expressed well via writing or manually due to my disabilities. But orally I can well at a slow pace. The very sentences I write now took about 30 years of hard work and determination to achieve. However doing written math was often not easy due to rubella. I understood math but did poorly on timed limited exams. During high school, my mathematics teacher worked with great imagination and respect to help me really enjoy math to the point he noticed I used math more as a conceptual tool in my creative life, rather than just making it through the next exam. Eventually, he felt I would make a good math teacher doing some research on the side. But what I didn't know was most of the college profs where unwilling to work my disabilities even though often I tutored my fellow math majors towards better grades. Eventually I dropped the math major. But promised myself someday I would return to math. I heard about personal computers coming on for doing mathematics. Perhaps someone would figure out how to do symbolic math on a PC. During the early 90s I was introduced to Mathematica at work (I was a lead software tester/gui designer) and at last I could enjoy math again due to its gui. But due to personal cost and office politics I was not to have access to Mathematica. One day I will. But the price of Mathematica just became higher and higher well beyond my reach. Focused instead on my graphics design as best I could. But never made enough to buy Mathematica. I gave up. Will I create a new proof or solve a long standing problem? Perhaps not, but I do enjoy the beauty of math and exploring equations. Then 6 days ago a friend told me about SAGE. Hope. Enough of me, You have a great back end of a large collection -- and growing -- of math tools/libraries etc. Perhaps taking some time to make inputting math functions/keyword/symbols into a cell might be a win-win for all. I always believed a computer should do the heavy work and allow me to work smart than hard. If you want I can prototype a new gui that would help me and email it to you.

As a hint to whoever wants to hunt this down if they get to it before
me: the original text of the cell is stored in a parameter passed to
tinymce when tinymce is initialized. This is passed in the data
attribute in the following code from cell.py (after the two patches are
applied).
if JEDITABLE_TINYMCE and
hasattr(self.worksheet(),'is_published') and no
t self.worksheet().is_published():
s +=
script$(#cell_text_%s).unbind('dblclick').editable(funct
ion(value,settings) {
evaluate_text_cell_input(%s,value,settings);
return(value);
}, {
tooltip : ,
placeholder : ,
// type : 'textarea',
type : 'mce',
onblur : 'ignore',
select : false,
submit : 'Save changes',
cancel : 'Cancel changes',
event : dblclick,
style : inherit,
data : %r
});
/script%(self.__id,self.__id,self.__text)
My guess is that something is wrong with this data parameter being
passed to the tinymce instance. If the data parameter is not passed,
then TinyMCE will use instead the html that is actually in the notebook,
which would be the formatted jsmath version, which is what the symptoms
indicate.

[sage-support] Re: python's list comprehension
Note that you're skipping the last conductor in the database, I think... DB.conductor_range? indicates that the returned values represent an inclusive range, but range/xrange/etc. take their second argument as an exclusive bound. (This is easy to fix with the above xrange expression, but I don't see how to fix it with the simple *args syntax.) Touche. I can find *a* way to fix it, but only at the cost of making it significantly uglier and more fragile than the original use of an anonymous lambda: sage: t = (1,10) sage: srange(*(list(t) + [1,ZZ,False,True])) [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] Clearly that's not the way to go in general ... I think the lambda is much nicer in this case. (To be fair, Scheme is still the language closest to my heart, so I may be biased.) -cc --~--~-~--~~~---~--~~ 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 -~--~~~~--~~--~--~---

What I'm trying to do is generate various 3-D plots of some affine
varieties. As a start, I have no idea how to plot the equation:
x^2 + y^2 - z^2 = 0
But for the equation
z^3 - zx^2 + y^2 = 0
I know that it describes three cones meeting at a common point.
