I observe the following in Python 2.6.1 in CentOS 5.9 and in Python 2.7.5 in MacOS 10.9.2.
A heapified 3-element array containing elements in the order [low, high, medium] fails to print in sorted order, as shown below:
>>> import heapq
>>> lista = [1, 6, 5, 4]
>>> heapq.heapify(lista)
>>> lista # Gives sorted order, as expected
[1, 4, 5, 6]
>>>
>>> listb = [1, 6, 5]
>>> heapq.heapify(listb)
>>> listb # Gives unsorted order -- unexpected and presumably a bug
[1, 6, 5]
>>>
>>> [heapq.heappop(listb) for i in range(len(listb))] # But heappop works
[1, 5, 6] |
