Are you aware of functools.partial?
>>> from functools import partial
>>> def f(a, b, c, x, y, z):
... return a*x + b*y*y + c*z*z*z
...
>>> fstar = partial(f, x=1, y=2, z=3)
>>> fstar(1, 0, 0)
1
>>> fstar(0, 1, 0)
4
>>> fstar(0, 0, 1)
27
>>> fstar.args, fstar.keywords
((), {'y': 2, 'x': 1, 'z': 3})
>>> fstar.func
<function f at 0x7fc4868e6848>
