The Python interpreters have socket.gethostbyname which is, I believe, a thin layer over the C function, but neither of the two major Python DNS implmentations (python-dns and dnspython source packages) do. They parse /etc/resolv.conf and generate their own queries, so if I understand it correctly the Python world would end up not even internally consistent.
