Thanks for the tips guys.

beatifull!
as somone that trying to study programing, i think the probblem with python is that in an excerice like this one, instead of study "how to think"- go over an array with a loop, and think what you need to do to replace somthing, python do it for you

write everything in one line doesnt make the solution better

strip() removes only first space
(WUB)+ replace all inline WUB with one space

is there a place for bisection serach instead search one by one?

finaly i know how to return in one line with if in dart, thanks!
and what if i want to return only if- positive? and lets say do somthing if not?

pay attention to the + in the regex

I was going for short rarther than quick. As long as it passed the tests, it was good enough.

why does it take almost double the time my long solution take? like i defined another class for the players, and did somthing much lesss elegant

sekulski, why is it have greater computational complexity than list of lens?

strip won't delete all the spaces>

no, sum just happens to accept a generator. That ord(c) for c in ... is a generator expression, and is not a list.

ord(c) for c in s.replace(' ', '')- I thought this semantic is for list comprehension, can i use it for every loop?
