Python QuerySet对象和或运算符

我是python新手，在使用djnago查询时发现了一些对象列表，如

 querysetObj = <QuerySet [<class: obj1>, <class: obj2>]>
 queryset=<QuerySet [<class: obj1>, <class: obj3>,<class:obj4>]>
 for obj in querysetObj:
   queryset|=obj 
 queryset=<QuerySet [<class: obj1>, <class: obj3>,<class:obj4>,<class:obj2]>#it acts like a set compare objects and add none repeated objects only 

querystobj=
queryset=
对于querysetObj中的obj：
queryset |=obj
queryset=您可以通过实现特殊的
\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
方法（也可能是
\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

如果左操作数定义了
\uuuuu或
，则调用其
\uuuu或
方法。如果它没有执行，或者抛出了
未实现的
，则调用右操作数的
错误

其他操作符的实现方式也类似，使用各种特殊函数。
它确实有效，我已经尝试检查DjangQuerySet不是列表，它们是QuerySet。例如，参见django罚单，了解它们添加到Yes中的位置，我想做相同的设计，但是对于普通类谢谢，我正在用我自己的类检查它
class Foo:
    def __or__(self, other):
        return "Orred Foo"
    def __ror__(self, other):
        return "Rorred Foo"

Foo() | Foo()
# => 'Orred Foo'
Foo() | 7
# => 'Orred Foo'
7 | Foo()
# => 'Rorred Foo'
