Shame I can't jump to your solution to vote it up, not only it's really clever it's much faster than top voted and mine.
To be exact most "clever" solution is 9 (!) times slower than yours.
Hate the way Codewars promotes writing functions in slow wank style as "Clever Best Practices" :/

what is the explanation @FedyakinRoman ?

He made some extra spaces and lose some necessary ones. You can check it in any "pep8 beautifier".

What did he ignore in terms of PEP8?

Fixed for python

Ethernal classic! :)

Today I learned about from_bytes/to_bytes.
Thank you!

I made some researching and it looks like you're right. In that case tuple should be little bit faster.

I'm by no means a Python expert, but in my understanding a tuple is a simpler and cheaper data structure than a list (because a tuple is immutable), and thus probably also faster.

Nice underestimated solution!

straightforward solution, but not the best practice
