Solve the following python programming problem given the following code:
def command_callback(self, uid, to, msgs) : 
    if isinstance (msgs, asyncio.Future) : 
        msgs = msgs.result () 
if (msgs is not None) : 
        def iterator(msgs) : 
            for msg in msgs : 
                (yield (to, msg)) 
if isinstance (msgs, string_types) : 
            msgs = [msgs] 
handle = self.context.call_many ('privmsg', iterator (iterator)) 
        if (handle is not None) : 
            self.handles [uid] = handle 

    
    

    Fix the buggy line: handle = self.context.call_many ('privmsg', iterator (iterator))

#Here is Python code to fix the buggy line: handle = self.

handle = self.context.call_many ('privmsg', iterator (msgs))
