Solve the following python programming problem given the following code:
def _test_get_cfg_agents_for_hosting_devices(self, assignable_agents, schedule = False, id_disable_cfg_agent = None) : 
    def faked_choice(seq) : 
        res = seq [self._current_index] 
        self._current_index += 1 
        return res 
if (id_disable_cfg_agent is not None) : 
        self._update ('agents', id_disable_cfg_agent, { 
            'agent' : { 
                'admin_state_up' : False, 
}, 
}) 
with self.hosting_device_template (host_category = self.host_category) as hosting_device_template : 
        hdt = hosting_device_template ['hosting_device_template'] 
        with self.hosting_device (template_id = hdt ['id']) as hosting_device1, self.hosting_device (template_id = hdt ['id']) as hosting_device2, self.hosting_device (template_id = hdt ['id']) as hosting_device3 : 
            hds = [hd ['hosting_device'] for hd in (hosting_device1, hosting_device2, hosting_device2)] 
            hd_ids = [hd ['id'] for hd in hds] 
            for hd in hds : 
                self.assertIsNone (hd ['cfg_agent_id']) 
ids_hd_to_assign = [hds [0] ['id'], hds [2] ['id']] 
            self._current_index = 0 
            with mock.patch ('networking_cisco.plugins.cisco.device_manager.scheduler.hosting_device_cfg_agent_scheduler.random.choice') as random_mock : 
                random_mock.side_effect = faked_choice 
                agents = self.plugin.get_cfg_agents_for_hosting_devices (self.adminContext, ids_hd_to_assign, schedule = schedule) 
                self.assertEqual (len (assignable_agents), len (agents)) 
                for agent in agents : 
                    self.assertIn (agent ['id'], assignable_agents) 
hds_after_dict = { hd ['id'] : hd for hd in self._list ('hosting_devices') ['hosting_devices'] } 
                hds_after = [hds_after_dict [i] for i in hd_ids] 
                if (len (assignable_agents) == 0) : 
                    for hd_after in hds_after : 
                        self.assertIsNone (hd_after ['cfg_agent_id']) 
else : 
                    self.assertIn...

    
    

    Fix the buggy line: hds = [hd ['hosting_device'] for hd in (hosting_device1, hosting_device2, hosting_device2)]

#Here is Python code to fix the buggy line: hds = [hd ['hosting_device'] for hd in (hosting_device1, hosting_device2, hosting_device2)]
.

hds = [hd ['hosting_device'] for hd in (hosting_device1, hosting_device2, hosting_device3)]
