Ok, I'll take a stab at it.

class DevList(object):
    def __init__(self, objs):
        self.devpool = objs

    def __getattribute__(self,attrname):
        if attrname == "devpool":
            return object.__getattribute__(self,attrname)
        def ret(*args):
            return [ getattr(p,attrname)(*args) for p in
self.devpool ]
        return ret


dl = DevList([1,2,3])
print dl.__str__()

prints:

['1', '2', '3']
