The pyamf.org (that has already been linked to) is great. An alternative (if you dont need the unserialized data server side) is to use byteArray. I pasted below a very scrappy example of how to get this working using Google App Engine (in python). Incidentally, the same GAE had a pyamf example in it, which I have left, but which is commented out. (The MXML/AS is first, then the python)
