If you call a function with an empty list like this print(find_average([])) This causes the error - ZeroDivisionError: division by zero

As long as the first test and further attempts don't fail it's the correct solution, simple as that. ^.^

This must surely raise division by 0 on numbers = []

[] that's an empty list, calling your function like this: find_average() you're not passing anything.

Everytime I try to pass an empty array: find_average()

I get the following error:
TypeError: find_average() missing 1 required positional argument: 'numbers'

So I guess it's not possible to pass an empty array because the array is the only argument for the function... In that case, is it really necessary to account for empty arrays with an if statement?

need to replace len(numbers) with (len(numbers) or 1) to cover empty arrays.

This isn't correct solution. As the case for correct answer in case of empty array(list) is missing.

Yes, but tests are lacking, there is an issue about that raised.

Wouldn't it display an error if len(numbers) = 0 ?

Literally, the exact same words that came out of my mouth.
