Raymond Hettinger added the comment:
Daniel, I've already been in the process of adding a class to the heapq module
and have done substantial work on it over the last few months. I'll look at
your code to see if there are any ideas that should be merged with it before I
finish it up.
Am

Daniel, I'm going to close this one so we can continue work in just a single
tracker item: http://bugs.python.org/issue17794
I'll see if anything in your code should be merged in to mine and will list you
as a co-contributor when it all goes in.

Antoine Pitrou added the comment:
queue.PriorityQueue is a locked class for use in multi-threaded code. That's
like saying Queue is a good substitute for list :-)
OTOH, the proposed patch raises a lot of warning signs for me. I will wait for
a decision on the feature's desirability before
Serhiy Storchaka added the comment:
From my multilingual experience I can say that priority queue is very rarely
used type of collections (but if it needed it is very usefull). On one hand,
Python stdlib already contains one such type, and this type will be good
enough in
New submission from Daniel Wong:
heapq already provides a bunch of functions for manipulating lists that
preserve (or create) a heap invariant. My change adds two classes for
representing heaps. These classes ensure that operations that violate the heap
invariant are not possible (through the

Daniel Wong added the comment:
Hey Serhiy,
Are you suggesting that I put my new classes in a new module and rename them? I
think it'd be better to keep them in heapq, unless someone intended to add more
classes to your proposed queue module, because heap functionality would be
spread between
R. David Murray added the comment:
Serhiy is pointing you to an existing use of heapq in the stdlib. I'm not
quite sure what his intent is in pointing it out, though it *might* be to point
out that heapq is a primitive, and PriorityQueue already implements a
subclassable class using it.
I
Daniel Wong added the comment:
Ah, Serhiy is pointing out that there's already a class named PriorityQueue in
the queue module. I didn't know that exists.
Now that I've had a chance to look at it, queue.PriorityQueue is like my Heap
class, but there are some interesting difference; moreover,
16 matches
