In Python, heapq.heapify doesn't take cmp or key functions as arguments like sorted does

Question

I\'m using python2.6. Is it available in higher version of python?
Else is there any other way I can maintain priority queues for list of objects of non-trivial classes?

Answer 1

Well, this is terrible and awful and you definitely shouldn't do it… But it looks like the heapq module defines a cmp_lt function, which you could monkey patch if you really wanted a custom compare function.
