161 – min-heaps and max-heaps

The module heapq has support for min-heaps and max-heaps, providing a number of functions to work efficiently with priority queues:

from heapq import (
    heapify,
    heappush,
    heappop,
    heappushpop,
    heapreplace,
)  # for min-heaps

For max-heaps, append the suffix _max to the name of each function:

from heapq import (
    heapify_max,
    heappush_max,
    heappop_max,
    heappushpop_max,
    heapreplace_max,
)  # for max-heaps

Support for min-heaps has been around for a while but support for max-heaps was only added in Python 3.14.
