While the only issue here was that you do not expect any code, just "STRANGE_STRING= ....".

Can you find a string that satisfies this criteria?

You should just set the value of STRANGE_STRING to meet the previous criteria.

Python initial code:

STRANGE_STRING = 'foo'

What is not clear there? You can argue about not having to write a function and code like in almost every other kata, but what you should do is written in the description.

While critique of descriptions is a fair thing, I would sincerely recommend adjusting your general attitude a little bit.

vaaaaaaaax! Don't I recognize you, whatt47? It seems like you leave a stream of havoc wherever you go.

Could you elaborate on the "expects us to hardcode wrong practices" part?

is far beyond the beginner's knowledge of Python

If you can't take the cocktail, maybe you should stick to lemonade.. Just remember, every great mixologist started with a simple recipe!

Pokud nezvládáte koktejl, možná byste se měli držet limonády. Jen nezapomeňte, že každý skvělý barman začínal s jednoduchým receptem!

Btw, 6 kyu is no longer beginner level.

"fraction of sum of items / number of items" is literally the definition of the expected value of a random variable :) More or less.

It is not an issue, this is how Codewars works.

perhaps there is an extra transition to the next line at the last iteration
