For Dijkstra’s algorithm, what would be a way to keep track of and store the vertices that each shortest path contains?

I have it coded it out to update all the costs of the edges and such to complete Dijkstra’s main goal of finding the shortest path from the source vertex to all other vertices. But I what I need help on is figuring out a way to store the vertices that each shortest path contains into an array that contains

FilterStore queue

priority-queue python queue simpy

I have a FilterStore and during my simulation there is a queue for the FilterStore.Get event at some times. Now I have two questions: Is there a way to see the actual elements in the queue, not just the object number? With FilterStore.get_queue I get this output: [FilterStoreGet() object at 0x221a47c6080, FilterStoreGet() object at 0x221a47c6eb8]. But I would like a

Can I get an item from a PriorityQueue without removing it yet?

I want to get the next item in queue but I don’t want to dequeue it. Is it possible in Python’s queue.PriorityQueue? From the docs, I don’t see how can it be done Answer When you get item form the queue as per theory it will remove from the queue. You have to write your own function which will give
