I'm assuming you can put this into a list like:

    failures = [failure1, failure2, failure3, ...]

A failure can be represented by a "namedtuple" or a class or some
other thing. For simplicity, I'll use a class:

    class Failure:
        def __init__(self, name, type):
            self.name, self.type = name, type

        def __repr__(self):
            return "Failure({}, {})".format(self.name, self.type)

You have your list of Failure()s, so you can do:

if all(fail.type == "new fail" for fail in failures):
    set_priority_1()

elif any(fail.type == "new fail" for fail in failures):
    set_priority_2()

elif any(fail.type == "P2 known fail" for fail in failures):
    set_priority_3()

elif any(fail.type == "P3 known fail" for fail in failures):
    set_priority_4()

elif any(fail.type == "P4 known fail" for fail in failures):
    set_priority_4()

else:
    freak_out()


If you want something else, I'm not sure what you're asking.
