Python copytree with negative ignore pattern

I am trying to use python to copy a file / directory tree.

Is it possible to use copytree to copy everything that ends in foo?

There is a function ignore_patterns patterns, can I give it a negative regular expression? Are they supported in python?

eg.

copytree (src, dest, False, ignore_pattern ('! *. foo')) Where! does NOT mean something that ends in foo. thank.
