I did your command and it is compiling. My problem was I have two
sagemath, and I forget to do ./sage
thanks it works

Please provide more details: what platform? What went wrong.
It worked for me, by the way:
$ ./sage -i database_odlyzko_zeta
...
Thanks for the explanations. I now know how to use the tab completion in
SAGE and it's useful.
Best,

SageMath's language is Python, in particular it is object oriented.
Personally, I'd always prefer calling a

Thank you to the people who responded, all answers were helpful.
Is there a difference between
return expand(f^2)
and
return (g^2).expand()
or are they perfect synonyms?
The same question for
lambda f: (f^2).expand()
(in Simon's answer): is the lambda construction just a shortcut, equivalent

You can try
sage: x= polygen(GF(2), a)
and try a few expressions involving x. For example
sage: 2*x
0
since 2=0 in GF(2).

How to do this symbolic algebra in GF(2)={0,1} ?
My need is the following:
I have a recurrence relation like z[t+6]=z[t]+z[t+3]+z[t+4]*z[t+5] in GF(2)
taking z[0]=a0,z[1]=a1,...,z[5]=a5

You could work in the polynomial ring generated by the ak, modulo the
relation ak**2 = ak:
P=PolynomialRing(GF(2),[a%d % i for i in (0,..,5)])
I=P.ideal([u*u-u for u in P.gens()])
Q=P.quotient(I)
@cached_function
def z(k):
if k 6: return Q.gens()[k]
return z(k-6)+z(k-3)+z(k-2)*z(k-1)
Thanks. It solves my problem.

So, when you write 3 in a .pyx file, it becomes a python int, but if
