I want to find coefficent of a polynomial ring. How to do this?

R.<x>=IntegerModRing(15)[] f=1+x^2+4*x^6

So coefficient of x is 0, x^2 is 1, x^6 is 4 etc. How to get these?

Does this solve your problem?:

R.<x>=IntegerModRing(15)[]
f=1+x^2+4*x^6
coeffs=(f.coefficients(sparse=False))
show(coeffs)
