How negative numbers becomes positive? This solution is outstanding
great solution

ok, that's your opinion, facts tell a different story on performance...
Just because it looks efficient, doesn't mean that it is. Python's built-in functions are implemented in C, which makes them way faster, than this reinvention in python.
Python's standard library functions are implemented in C, so not only is this solution cleaner, it's also significantly faster, than your reinvent-the-wheel solution.
Get ahead with the times, people! /j

It has two lines of code less than mine
