In my Sage code,

R.<v1, v2, v3>=BooleanPolynomialRing(3)
f=v1*v2+v1*v3+v1
print f.coefficient(v1)

I am getting

Traceback (click to the left of this block for traceback)
...
AttributeError: 'sage.rings.polynomial.pbori.BooleanPolynomial' object
has no attribute 'coefficient'

Answer should be v2+v3+1. I do not want

to use R.<v1, v2, v3>=GF(2)[] as in this

ring  operations are much slower than
R.<v1, v2, v3>=BooleanPolynomialRing(3).
