Thank you for taking the time to explain this, I would like to offer some feedback as a way to repay you! You can actually simplify these for loops you're writing by doing something like ``` if currStop in visited_stops: continue # go to the next iteration # else cur stops is not visited here then do the logic in the if statement ``` Same thing for the final for-if-for-if combo, that way you can improve the code layout a little bit. Also you could use `defaultdict` from collections to do something like. ``` stopToRoutes = defaultdict(lambda: set()) for route in range(len(routes)): for stop in routes[route]: stopToRoutes[stop].add(route) ```
