If you mean a module in the distribution, the answer is no, for
political reasons.

There are a number of AES modules available on the net.  Most are C
extension modules which means you need to compile them, and if you
want to deploy them widely, you need binaries for every target platform.
There's a few pure-Python AES implementations but they are verrry slow.

Here's something written in Python that uses the built-in sha1 module
as a crypto primitive.  Its security should be better than rotor and
performance is reasonable for most applications:
