This is a clever use of exceptions, though I would avoid this in production code. Raising exceptions is costly, and also if "a" happens to be a long string you would be creating a string 50 times larger.

good use!

Thuis a brilliant codewar

u sure that this is a good option? ty

so pythonic

it actually takes less time if you use it once

instead of importing entire module you can just say from math import floor

I think that the point of this kata is try to resolve it without using these functions.

This is absolutely simple.

not need to put list()

ahhahaaaa!
