WebThe DFS is an algorithm used to traverse the target node in a graph or tree data structure. The depth-first search derives from the word "depth". Its priorities depth and searches along one branch, as far as it can go - until the end of the branch.

It would be better if you used a raw list as people are more familiar with lists then a custom Stack class.. When using a plain Python list the while loop can take advantage of lists being truthy if they have items. This allows you to do while stack: instead..
