我正在寻找一种优先级队列，该队列可以给我两个优先级。我希望它只检查第一个值，然后检查第二个值，这是一些代码
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'))
现在我想要元素的以下顺序
Important job
Mid_level job
Low_level job
如何使用一个队列创建这样的订单？
class Job(object):
def __init__(self, fpriority, spriority, description, iata , hops, cost):
self.fpriority = fpriority
self.spriority = spriority
def __cmp__(self, other):
'''Comparisons for Python 2.x - it's done differently in 3.x'''
if self.fpriority > other.fpriority:
return 1
elif self.fpriority < other.fpriority:
return -1
else:
if self.spriority > other.spriority:
return 1
elif self.spriority < other.spriority:
return -1
else:
return 0
