[Tutor] calculating a sort key and operator.attrgetter()

[Vincent Davis]

I have a class with an attribute which is a list "rank_list" this is a list
of instances f another class that has attributes "quality, is_observed"
if I want to sort the list by the attribute "quality" I can just use,
self.rank_list.sort(key=operator.attrgetter('quality'))
But I want to sort like this.
self.rank_list.sort(key=(operator.attrgetter('quality') *
operator.attrgetter('is_observed') * self.does_observe))
Will this work or is there a better way?

Thanks
Vincent Davis
