It's really easy.  Here's an example that just prints to stdout.  If
you haven't already, spend an hour or two and peek at the Python
tutorial at:

http://www.python.org/doc/current/tut/tut.html

It's really easy to pick up; took me a day or two.

Anyway, I'm not sure if PGP/MIME uses application/pkcs7-mime or
multipart/signed in real life; this example deals with both.

#!/usr/bin/env python

import email
import sys

if len(sys.argv) != 2:
    print "Usage: %s filename" % sys.argv[0]
    sys.exit(1)

fd = open(sys.argv[1])
msg = email.message_from_file(fd)

if msg.get_type() in ['multipart/signed', 'application/pkcs7-mime']:
    body = msg.get_payload(0)
    sig = msg.get_payload(1)
    print "===body===\n" + body.get_payload() + "\n"
    print "===sig===\n" + sig.get_payload() + "\n"
else:
    print msg.get_payload()
