Priority Queues in Python

from queue import PriorityQueue

q = PriorityQueue()

q.put((2, 'code'))
q.put((1, 'eat'))
q.put((3, 'sleep'))
q.put((4, 'play'))

while not q.empty():
    next_item = q.get()
    print(next_item)

# Result:
#   (1, 'eat')
#   (2, 'code')
#   (3, 'sleep')
#   (4, 'play')

python 好像没有 buildin 的方法能把(3, 'sleep')改成(1, 'sleep') 有没什么好的方法可供参考。
