Nice solution! Could just be my current comfort with the language, but I don't find this as easy to read and understand as some other solutions with similar time complexities though.

Genial

but is fast lol

if both key and anwser is "", what's the expect? 4 or 0 ?

self.x returns the same thing as self.__dict__['x']

__dict__ is the internal dict of the class.

How does it work? Can someone explain?

This is what I wanted to do, but eventually gave up... Great to see!

another one who wanna show off their skills (not ot mention I'M FUcING 8KYUUUUU)

hahaha you are right but this is what codewars is about to use your brain and give your best

You know one is free to do whatever he fancies?

We don't do that here, screen space is expensive (that was sarcasm, of course).

You know you don't always have to write a one liner.
You can write the same code spaced out into 3 or 4 lines.
Doesn't hurt anyone, rather reduces confusion.

I agree, but I also believe that a solution should only be optimised if it times out.

great
