I think it's better to do something like:

class nameA:
     def __init__(self, sema):
         self.sema = sema
         <other stuff>

     def run(self):
         <do some stuff>
         self.sema.release()

class nameB:
     def __init__(self, sema):
         self.sema = sema
         <other stuff>

     def run(self):
         self.sema.acquire()
         <do some stuff>

Then where you create instances of those classes:

sema = threading.semaphore()
a = nameA(sema)
b = nameB(sema)


Maybe you don't even need the semaphore at all: have a look at 
Queue.Queue, it might do exactly what you need.
