Solve the following python programming problem given the following code:
def call(self, command, opts = { 
    
}, on_response = None, on_notify = None, on_error = None, wait = False, timeout = None, id = None) : 
    args_cmd = 'hsdev {0}'.format (opts) 
    call_cmd = 'hsdev {0} with {1}'.format (command, opts) 
    if (not self.verify_connected ()) : 
        return (None if wait else False) 
try : 
        wait_receive = (threading.Event () if wait else None) 
        x = { 
            
} 
        def on_response_(r) : 
            x ['result'] = r 
            call_callback (on_response, r) 
            if wait_receive : 
                wait_receive.set () 
def on_error_(e, ds) : 
            call_callback (on_error, e, ds) 
            if wait_receive : 
                wait_receive.set () 
if (wait or on_response or on_notify or on_error) : 
            if (id is None) : 
                id = str (self.id) 
                self.id = (self.id + 1) 
self.on_receive (id, args_cmd, on_response_, on_notify, on_error_) 
opts.update ({ 
            'no-file' : True, 
}) 
        opts.update ({ 
            'id' : id, 
            'command' : command, 
}) 
        msg = json.dumps (opts, separators = (',', ':')) 
        self.hsdev_socket.sendall (msg.encode ('utf-8')) 
        self.hsdev_socket.sendall ('
'.encode ('utf-8')) 
        log (call_cmd, log_trace) 
        if wait : 
            wait_receive.wait (timeout) 
            return x.get ('result') 
return True 
except Exception as e : 
        log ('{0} fails with exception: {1}'.format (call_cmd, e), log_error) 
        self.connection_lost ('call', e) 
        return False 

    
    

    Fix the buggy line: args_cmd = 'hsdev {0}'.format (opts)
