Priority Queue with two Priorities Python

Question

I'm searching for a kind of priority queue which allows me to give two priorites. I want that it just check for the first value then for the second one Here is some Code

import Queue

class Job(object):
    def __init__(self, fpriority, spriority, description, iata , hops, cost):
        self.fpriority = fpriority
        self.spriority = spriority

q = Queue.PriorityQueue()

q.put(Job(2, 5, 'Mid-level job'))
q.put(Job(2, 20, 'Low-level job'))
q.put(Job(1, 20, 'Important job'))

now i want the following order of the elements

Important job
Mid_level job
Low_level job

how can i create such an order with one queue?

Answer 1

Just use the (fpriority, spriority) tuple as the priority. That'll do the sorting you want (compare first, then second to break ties).
