Pretty cool when it appears. You can edit it, and the examples are written in a way that the output helps explain the flow (like showing the pivot and array state in each pass of a quicksort). I'm surprised it doesn't support Javascript though, since it's now so popular.
It also doesn't seem to support anything advanced or synonyms for terms. I can search for "Reverse array python" but not "Reverse list python" (technically a list is the proper name, and array is a different construct in Python), and anything more advanced than sorting algorithms or simple features don't appear. I tried a few pathfinding algorithms, fibonacci sequence, prime numbers.... And I tried several variations of search terms. "Pathfinding in Pyhton" / "Graph Search in Python" / "Djikstra's algorithm in Python", nothing. I don't think it will be very useful because of this.
