That's a very in-depth article!

I really should spend some time using the various features of itertools module.

itertools is just awesome :)

The double iterator loop is pretty awesome.

Which one are you talking about?

for prev_, next_ in zip(prev_it, next_it)

Ah yes, that's an interesting one :)

Great article, but I do wonder. I used a simple for loop with a lastVal-Variable which gets overridden each loop. Would this be considered an anti-pattern? Seemed like the most simple/readable solution and no need to mess with indices.

For the second part I used pandas rolling sum, a somewhat lazy solution.

I don't think that's an anti-pattern. I'm just personally not a fan of doing too much bookkeeping with my variables :p
