nope, the problem description includes this:

Assumptions

• You can assume that you are only given numbers.

if we're ever passed a list that includes non-numbers, it's the code calling our function that's breaking the contract, not us

you are not alone

Didn't we have to consider that array element could be not a number?

oh I just learned how to use "not in" recently but I forgot to apply it.

same here LOL

:P

and then of course, there's this

biggest facepalm i ve ever had

Haha clever

when using list comprehensions, if you have no else to add, you should use the if after the for not before it. I guess that's the reason
try it yourself.

Very simple to use ;)

😎it`s me

and here I assumed I couldn't just sort a string...

Useful when you want to learn 'not in' list

My solution... Lol :)
