Can somebody explain this syntax to me? I understand tuple([1,1,1]), but
what are the curly brackets and the colon doing?
The argument is a python dict, which you should read up about for more
details.
Thanks, that's exactly what I needed to know!
Also, is there a reason that A.monomial([1,1,1]) does not return the same
result?
You did not make precise what type your A is but if I define
sage: A.<x,y,z> = QQ[]
sage: A
Multivariate Polynomial Ring in x, y, z over Rational Field
sage: type(A)
<type
'sage.rings.polynomial.multi_polynomial_libsingular.MPolynomialRing_libsingular'>
then A has no method called "monomial".
Very true. I suppose what I was asking was, would it be useful to human
beings who are not me to wrap the python-esque syntax in a Sage
function? And if so, is "monomial" the right thing to call the
function, or should A.monomial() naturally refer to some other operation?
