1Initialize the source node to take value 0 and all other nodes to ∞. 2) Find all neighboring nodes and update their values to either the minimum of their value or the value of the current node plus its distance. 3) Assign the minimum-valued unfinished node as the current node.
Dijkstra's algorithm uses a priority queue, which we introduced in the trees chapter and which we achieve here using Python's heapq module. The entries in our priority queue are tuples of (distance, vertex) which allows us to maintain a queue of vertices sorted by distance.
