How can I communicate with mainthread?

lass Enemy(pyglet.event.EventDispatcher):
def init(self):
self.life = 10
self.position = 0, 0

def show_at(self, position):
    self.position = position
    self.dispatch_event('on_enemy_born', self)
    print("send event")

def take_damage(self, damage):
    self.dispatch_event('on_enemy_under_attack', self)
    self.life -= damage
    if self.life < 0:
        self.dispatch_event('on_enemy_destroyed', self)

Enemy.register_event_type('on_enemy_born')
Enemy.register_event_type('on_enemy_under_attack')
Enemy.register_event_type('on_enemy_destroyed')

class BattleField(cocos.layer.Layer):
def init(self):
super(BattleField, self).init()

def on_enemy_born(self, enemy):
    print("recv event")
    enemy_sprite = cocos.sprite.Sprite('images/enemy.jpg')
    enemy_sprite.scale = 0.5
    enemy_sprite.position = enemy.position
    self.add(enemy_sprite)

def create_enemy(total, where):
n = 0
while n < total:
n = n + 1
enemy = Enemy()
enemy.push_handlers(where)
random_x = random.randint(0, 640)
position = random_x, 240
enemy.show_at(position)
time.sleep(1)

if name == "main":
cocos.director.director.init()
bg_layer = BackGround()
battle_field_layer = BattleField()
thread = threading.Thread(target=create_enemy, args=(10, battle_field_layer))
thread.start()
main_scene = cocos.scene.Scene(bg_layer, battle_field_layer)
cocos.director.director.run(main_scene)

Above is my code,I am trying to add enemy dynamic from other thread. It keep raising the GLException.
