you should have handled array overflow

Not the best practice cuz any other type of n then int will return -1.

Didn't event think of catching errors on these fundamental tasks...I like it.

Not the best practice as any other errors that are not due to IndexErrors will still return -1. Its best to return -1 ONLY when index is out of range.

Got it. Thank you very much for your help!

hmm.. i think you need to get some undrstanding of pass by value / pass by reference in general. And how it works in python.

You can check something like this: https://www.geeksforgeeks.org/pass-by-reference-vs-value-in-python/

Hope you'll answer your own questions after this =)

I'm a little confused by array[n].

Isn't this used to look up in a list/dict?

array is a parameter. Don't we need to create a list first?

I'm new at this.

Thank you very much!

bare excepts are a good example of what not to do. So this is exactly NOT best practice.

I agree on both counts; catching exceptions is good and handling expected states is great.

In case of negative index it's definitely the best practice.
