python的asyncio中的可加入PriorityQueue(Joinable PriorityQueue in python's asyncio)

 根据文档 ，有几种Queue实现。 我感兴趣的是JoinableQueue和PriorityQueue，因为我想拥有一个具有优先级的可连接队列。 
 
 似乎我只能获得较低版本中的一个功能。 即在3.5中我可以使用Queue（可连接）和PriorityQueue进行区分，但是在3.5以下的python中有JoinableQueue和PriorityQueue（参见下面的示例）。 
 
 是否可以将它们组合起来以获得在3.4中获得可连接的PriorityQueue的一般方法？ 
 
try:
    # Python 3.4.
    from asyncio import JoinableQueue as Queue # joinable
    from asyncio import PriorityQueue          # I assume this one is not joinable
except ImportError:
    # Python 3.5.
    from asyncio import Queue                  # standard joinable
    from asyncio import PriorityQueue          # I assume this is the one I want
 
 另一种方法是以某种方式影响队列？ 

As per the documentation, there are several implementations of Queues. The ones I'm interested in are the JoinableQueue and the PriorityQueue, as I'd like to have a joinable queue with priorities. 
 
It appears that I can only get one of the functionalities in the lower versions. I.e. in 3.5 I can make the distinciton with Queue (which is joinable) and PriorityQueue, but in python below 3.5 there is JoinableQueue and PriorityQueue (see example below).
 
Is it possible to combine them to get a general way to get a joinable PriorityQueue in 3.4?
 
try:
    # Python 3.4.
    from asyncio import JoinableQueue as Queue # joinable
    from asyncio import PriorityQueue          # I assume this one is not joinable
except ImportError:
    # Python 3.5.
    from asyncio import Queue                  # standard joinable
    from asyncio import PriorityQueue          # I assume this is the one I want
 
Another approach would be to somehow perhaps influence Queue?
