Does it need the enumerate command? I think my solutuon was similiar without it, is there any performance bennefit either direction?

I think it is best practice because it produced a concise and understandable solution within the constraints outlined by the problem. The problem never required specific exceptions to be caught.

You don't need to in this case. This isn't faster or more efficient than other solutions and is less readable

This is not efficient

This is not best practice as you don't catch specific exceptions. This would be poor practice

Probably because it is inefficient

This will be inefficient with large arrays

Except this doesn't work for numbers greater than 9. See my solution for one that does
