Yes. I guess the fact that there are at least 3 possible reasons is enough to have more "clever" than "best practice" :-)

It's impossible to answer this question, this is just what people voted, each one may have their reason.

BTW, I was wondering why this solution is rated more "clever" than "best practice".
It's because of the use of import, or because it's "one-liner" or because it uses a "regex"?

I really like this solution with no imported module.
Just I think it would have been easier for me to undestand with a different choice of variable names ("lines" instead of "parts" and maybe also "line" instead of "v" and "m" instead of "s").

I came up with a similar solution. I used a dictionary to store peaks and pos so we don't need a second loop.

Kata says function "takes a list of non-negative integers and strings"
