how can I make it work?

Show all headers | View raw

it's a finder using threading to accelerate but it never works..
and I have no idea why it doesn't work:(
it doesn't work too after changing threading to multiprocessing..
how can I make it work? or at least I know what's the problem...
plz help the poor newbie...



    import os,threading,multiprocessing


    def finder(path,q):
     for x in os.walk(unicode(path)):
      if x[1]:
       for dirname in x[1]:
        if target in dirname.lower():
         q.put(os.path.join(x[0],dirname))
      if x[2]:
       for name in x[2]:
        if target in name.lower():
         q.put(os.path.join(x[0],name))

     q.put(1)

    def printer(q):
     cmd=0
     while 1:
      tmp=q.get()
      if tmp==1:
       cmd += 1
       continue
      if cmd ==thnum:
       break
      print tmp

    if __name__ =="__main__":
     q=multiprocessing.JoinableQueue()
     ini=os.walk(u"C:\\").next()
     thnum=len(ini[1])
     target=raw_input("what you wanna get\n")

     p=multiprocessing.Process(target=printer,args=(q,))
     p.daemon=1
     p.start()

     for i in xrange(thnum):
      t=threading.Thread(target=finder,args=(ini[1][i],q,))
      t.start()
      print i," started"
     q.join()
