Instead of creating two of the same list for the if and for, you could've assign a variable.

Mutation tho

When you don't care to just make an average variable

LOL

perfect solution

hecker boi

Someone had to do it...

🤣

Love it

* Tuple Unpacking

Can anyone explain the *?

If len(arr) is 0 (empty list), then the if is false and returns an empty list. Without that part of the code it would return [0, 0] if len(arr) is 0

My solution has five lines and still fast :P

Check my code for a more optimized version of your def get_sum
