Consider the boolean variables x, y and z.
I need something like
sage: variables(x+yz)
[x, y, z]
sage: variables(x+z)
[x, z]
What should I do?
For a starting point, you may like (copied from the answer given here):
sage: R = BooleanPolynomialRing(3, 'x')
sage: x, y, z = R.gens()
You should read the doc before asking such questions here.
In particular, give a name to your object and use the automatic TAB-completion to get the list of available methods. In this way, you can learn about the methods .degree and .variables by hitting the TAB key after too.
sage: sage: R = BooleanPolynomialRing(3, 'x')
sage: sage: x, y, z = R.gens()
sage: too = x+z
sage: sage: too.v # (pressing TAB key here)
too.variable too.vars_as_monomial
too.variables too.version
sage: too.variables()
(x0, x2)
sage: len(too.variables())
