If you want to preserve insert order in case of duplicates, you can do this: from queue import PriorityQueueĪnd proceed similarly with heapq. In that case, it depends how you want to deal with duplicate values. If you have duplicate values, then the comparison will look at the second element of the tuple, and will break because your Nodes are not comparable. With queue.PriorityQueue, use tuples as suggested by the doc from queue import PriorityQueue P.queue # Īnother way, if you can specify the priority of each element as you push it in. Then just add them normally: p = PriorityQueue() Or if you want to just pass Node objects that exist already: ComparableNode: So you can wrap it in a class that you create. Let's assume you have this setup: class Node:īut you can't modify Node. One solution, without passing a comparator, is to wrap your Node objects in another object, say ComparableNode, which implements the comparisons you would like on the Node object.
