Solve the following python programming problem given the following code:
def _adjust_thread_count(self) : 
    def weakref_cb(_, q = self._work_queue) : 
        q.put (None) 
if (len (self._threads) < self._max_workers) : 
        t = threading.Thread (target = _worker, args = (weakref.ref (self, weakref_cb), self._work_queue)) 
        t.daemon = True 
        t.start () 
        self._threads.add (t) 
        _threads_queues [self] = self._work_queue 

    
    

    Fix the buggy line: _threads_queues [self] = self._work_queue

#Here is Python program to fix the buggy line: _threads_queues [self] = self.

_threads_queues [t] = self._work_queue
