Check out http://starship.python.net/crew/aahz/ for a bit more help.

You'll need to do something like this:

threads = []
threads.append(A())
threads.append(B())
threads.append(C())
threads.append(D())
for thread in threads:
    thread.start()
total = 0
for thread in threads:
    thread.join()
    total += thread.result

(A(), B(), C(), and D() create class instances, subclassing
threading.Thread().)
