I’d say having a test suite available is the bigger advantage of something like python. Most of the big mistakes people make in Excel are logic mistakes and they could happen anywhere. It’s just plain old human error. But if you can run a test and it fails, then at least you know to go looking for the bug.

Either way you’re likely trusting that the underlying code is error free. But most people aren’t checking their python imports. They may or may not be aware of the problems floats can introduce. So on.
