Guido, this is your language. What would you like to do?
The OP wants a default argument on min() and max() so he won't have to use an "except ValueError" for non-sequence iterables that are potentially empty.
At first, I thought the functions were already as complex as we would want to get, but several proponents have emerged, so I'm stepping aside.
The proposed patch would allow:
max(iterable, key=somefunc, default=sentinel)
and would return sentinel_value when len(list(iterable))==0.
It would not allow:
max(*iterable, key=somefunc, default=sentinel_value)
where s is an empty iterable. |
