Someone may implement a function like sum() (just an example) that looks like the sum of a long list of items is the first item added to a slightly longer sum of the remaining items. It stops when the final recursive sum is about to be called with no remaining arguments. Clearly this implementation may be a tad slow. But does Python require this version of sum() or will it allow any version that can be called the same way and returns the same results every time?

That's also true of C and pretty much every language I know of. They
define semantics, not implementation.
