Is this the sort of thing you had in mind?
sage: M=ModularSymbols(11,2);M
Modular Symbols space of dimension 3 for Gamma_0(11) of weight 2 with
sign 0 over Rational Field
sage: b = M.basis()
sage:
sage: s1 = 2*b[1] - b[2
We would like to know if certain sums of modular symbols span the
space. For a simple example, let
sage: M=ModularSymbols(11,2);M
Modular Symbols space of dimension 3 for Gamma_0(11) of weight 2 with
sign 0 over Rational Field
sage: M.basis()
((1,0), (1,8), (1,9))
Now, say we have three sums of
great- thanks, I thought there's an equivalent one in sage since there's
equivalent to functions such as range, xrange, etc. Just want to make sure
that I don't write my own function if one already existed.

While I don't think there's one readily available, you can easily define one
yourself:
def senumerate(seq):
return ((ZZ(i), x) for (i,x) in enumerate(seq))
Hoep this helps.

Try srange and sxrange/xsrange.

Works!! So, how do I make this permanent? I thought I set the

Dear all,
I just compiled sage from source (since the binary did not work for me) in
ubuntu 11.04 (in particular, lubuntu). I followed the instructions and the
compilation seemed to be successful. Also I set the permissions correctly.
However, when I run sage, I get a long message, which I attach
The enumerate function in Python has the index type as 'int' instead of say
sage's Integer. is there an equivalent of enumerate in Sage that returns
Integer type ? Thanks

Hi John,
I don't know if I have a good solution to your question.
At least, let me bring your question back to the first screen (perhaps
someone else has a better solution?) and try to explain my not-so-nice-
