Personally I used CodeCademy to learn the basics and rely on W3Schools to get a reminder of the correct syntax to use when I am not sure. Do not hesitate to Google what you are trying to achieve if you suspect that something already exists to do so in Python's built-in methods. I cannot speak for everyone there but this is what worked best for me so maybe it will suit your learning style as well !

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
>>>
