Group List Elements according to the Input with the order of binary combination

[quest_]

Very interesting. Is that a different package? I'm not on ubuntu, so just installed via pip.

For this package, the iterable is the first argument.

>>> import inspect
>>> import more_itertools
>>> inspect.signature(more_itertools.grouper)
<Signature (iterable, n, fillvalue=None)>

I did not check the version explicitly but yeah it made me very angry. Luckily I found. Btw I found from documents ... Maybe they just updated ...
