This is perhaps a naive question, but I couldn't find it anywhere.
Suppose I have an element of a modular symbol space, which Sage is
able to output as a linear combination of Manin symbols. Is there a
way to get Sage to give me back an individual coefficient of a
particular basis element in that

Here you probably mean something else. Are you getting a deprecation

I know this for the Sage prompt, but it doesn't work in a Python file
because without the preprocessing it tries to eval

It's better to define
a(x) = x
b(x) = 2*x

And, as we know now, if we do this in the notebook, we can even change
the value of 2 afterwards:
def f(x):
return 2*x
print f(3)
_sage_const_2=3
print f

Certainly it is a good idea.
Concerning feasibility: I am not
Hi!
The most straight forward way does not work:
sage: def bla(x):
: print "here I am"
: return x**2
:
sage: foo = function("foo", nargs=1, eval_func = bla)
sage: foo(5)

Hi all,
I'm trying to properly attribute sage in my master's thesis, and I
need to know what components (pari, etc) or which authors I need to
cite given that I used the following:
1. I used
E=EllipticCurve([-2,5])
E.gens()
for one explicit calculation.
2. I used (where f is a polynomial)
L.
Here is an example.
sage: from sage.misc.citation import get_systems
sage: get_systems('E = EllipticCurve([-2,5])')
['Singular', 'ginac']
sage: E = EllipticCurve([-2,5])
sage: get_systems('E.gens()')
['PARI', 'mwrank', 'Singular', 'FLINT', 'MPFR', 'ginac']
Note that I have to actually do the comm
