Nice use of itertools.groupby. Looks a bit tricky, but I get what you’re doing with the set of tuples. Thx for your code.

I saw nearly the same solution in another Random Review. Same comment here: Clever idea to use groupby and fill the signals into a set! The if int(k) is also tricky (just for readability I would write if int(k) != 0). Good job!
