Same. I find lots of really cool and clever answers on here get "best practice" dispite them being not the greaters options for code being maintained by a large amount of people.

I am also confused on how p0 = p0 * (1 + pecent/100) + aug works.
does the 1+ replace the need for p0 += p0 * percent/100 + aug?

When I test it myself it seems to work. It passes all but 1 off the sample tests and fails most of the random ones. Anyone know why?

I'm new to this, never realized there was a global function.

Guess I wanted to take the long route.
