function factory question: embed current values of object attributes

I have a class `X` where many parameters are set
at instance initialization. The parameter values
of an instance `x` generally remain unchanged,
but is there way to communicate to a method that
it depends only on the initial values of these parameters
(and does not need to worry about any changes)?
The behavior of method `m` depends on these parameter values.
It turns out `m` gets called a lot, which means
that the pameter values are accessed over and over
(self.p0, self.p1, etc). I would like to
manufacture a function equivalent to the method
that simply uses fixed values (the values at the
time it is manufactured). I do not care if this
function is attached to `x` or not.
I have a feeling that I am turning something simple
into something complex, perhaps for lack of an
afternoon coffee or lack of CS training. Suggestions
appreciated.
