Splet11. jan. 2024 · In this post, we’ll see an implementation of shortest path finding in a graph of connected nodes using Python. The shortest path will be found by traversing the … SpletInstead of putting True in the graph matrix, put a back-reference to the previous position in the graph (where you came from to get here). With that information you can find back the complete path you have travelled to get where you are. Here is what to put in the if.Make sure to change also the one-but-last line of your shortest_path method:. def …
