为什么我的异常会给出语法错误

Question

well new to django and python the website i'm making is an ecommerce website and it has a carts app which deals with the shopping cart in the views.py file i have this function :

  def get(self, request):
    try:
        item_id = request.GET.get('item')
        quantity = request.GET.get('qty', 1)
        delete = request.GET.get('delete', 'n')
        cart, is_deleted, cart_item = self._process_cart(item_id, int(quantity), delete, request)
        cart_count = cart.total_count
        request.session['cart_count'] = cart_count
        return Response({'success': True,
         'deleted': is_deleted,
          'count': cart.count,
          'item_total': cart_item.item_total,
          'cart_price': cart.cart_price,
          'cart_count': cart_count}, status=status.HTTP_200_OK)
    except Exception as error:
        print error

it always gives an invalid syntax error
