I see that Python 2.5 will include a simple implementation of any/all. What I would like to ask, before it's too late, is if it's possible to add an optional test argument.
any(iterable, test=bool) and all(iterable, test=bool)
These would be the new proposed APIs. The usecase is to be able to extract
attributes from objects or simply to have arbitrary checks like:
import operator
any(some_objects, test=operator.attrgetter('some_attribute'))
or
def zerop(x):
return x==0
all(some_objects, zerop)
instead of preprocessing the generator with a generator expression before
passing it to any/all.
Thanks.
