How to reorder terms in a polynomial to follow a specific order.

asked 2021-04-09 00:44:31 +0100

Hi everyone,

I have code in Sagemath that will give me various polynomials. However, I need these polynomials to be ordered in a specific way. For example, my code will output a polynomial that looks like this:

t^2-t+1

but I need it to be outputted like this:

1-t+t^2.

Is there any way to do this? Thanks, I appreciate the help.

For displaying the polynomial, you could convert it to a power series, which are ordered the other way around:

sage: var('t');
sage: f = t^2 - t + 1
sage: R = PowerSeriesRing(QQ, 't')
sage: print(R(f))
1 - t + t^2
