Awesome solution, definetly easier to understand than the others

Cant say for sure what is causing the issue unless you post more details or the exact code you using.

I kept getting a type error, saying the interpreter couldn't concatenate 2 types together. And I designated the str() around the index call.

thanks...i am looking for this kind of solution

Same issue; tried both of these approaches (round & float).

don't know how about you, but for me even round(n,2) didn't work...
despite the solution using round(n,2) passed obviously

Don't work for 2.675.
