how do you actually know all of this stuff

Wow

wow!

This solution is much better than mine.
So I'll be criticizing the use of camelCase when the code has already used snake_case, and I'll also note (although no one asked me to) that in English the plural word "sheep" is written the same way as in the singular, without adding the "-s" ending.

at runtime i forgot about this method :)

Remember snake_case!

Didn't expect such simple solutions exist

nah, you probably put something like this just phrased differently

I would settle for 'arrayOfSheep' just to deal with the grammar issue. :)

Oh?

>>> count_sheeps([])
0
>>> count_sheeps([False])
0
>>> count_sheeps([False, False])
0
>>>

This doesn't work if, there is no "True" in the list. This code gives you a None and a None is not a 0. Like they want it in the test.
