Can you elaborate a bit on what you mean?
Given a list of unique elements, it is easy enough to produce a
complete permutation generator in Python,
in the sense that it yields every possible permuation.
(See my previous post.)  So you must mean
something else?

Cheers,

PS If the elements are not unique, that is easy enough to
deal with too, as long as you say what you want the
outcome to be.
