Actually, it might be useful to allow a default value in general. (In typed functional languages, you often specify a default, or use a type that has a default value, so max(list[A]) can always return an A.)

Then again, you can write this pretty easily yourself:

    def my_max(iterable, *, default=_sentinel):
        try:
            return max(Iterable)
        except WhateverEmptyIterableRaises:
            if default is _sentinel: raise
            return default
