whoops

Last line of the kata: The array will never be empty.

Also 8th kyu kata are introductory, so error handling would be too advanced for this kata.

Doesn't handle:

• empty list
• bad data where list has elements of None

Nice! I wanted to do something like that but didn't know how!

That was a false intuition I had at that time because... this approach passed the tests (which are pretty insufficient). I've been proved wrong about that with other problems.

@Blind4Basics I am also interested in why checking one subsquares is enough as well.

Looks like a good example of how to use map.

@Blind4Basics: any explanation why checking only one subsquare is enough ?

More precisely,

// is always floor division.

In Python 2, / is contextual, and when used with int it is floor division, when used with float it is true division.

In Python 3, / is always true division.

In Python 3 // is floor division while / is true division. In Python 2, both are floor division

What is the diffeence between / and //?

Like the double-slash for clarity.

lol

Oh, I see. Thank you for your answers!
