Just as you are trying to do.

Does this help?

>>> class test(t.Thread):
...   def run(self):
...     print 'hi'
...     self.terminated = 0
...     import time
...     while not self.terminated:
...        time.sleep(1)
...     print 'done'
...
>>> te  = test()
>>> te.start()
hi
>>> t.enumerate()
[<test(Thread-2, started)>, <_MainThread(MainThread, started)>]
>>> te.terminated = 1
>>> done

>>> t.enumerate()
[<_MainThread(MainThread, started)>]

Your problem is that (a) you don't have a run() method in 
your thread class, and that is what gets executed when you
call te.start(), and (b) your thread is therefore terminating
immediately upon creation, and therefore t.enumerate()
is returning only the main thread, because no others are
running.
