Witryna29 wrz 2016 · Sep 28, 2016 at 20:25. The priority queue data structure is implemented in the python library in the "heapq" module. You can do Djikstra without it, and just brute force search for the shortest next candidate, but that will be significantly slower on a large graph. You say you want to code your own.
