I think there's a typo in:
Note that any change to the contents of a DeHeap (and
therefore a DeHeap2) any re-arrange the indices of a
number of entries in the DeHeap.
A useful Python class will follow Python convention, where
relevant convention exists. In this case that means optionally
passing the ordering relation; look at sort() and sorted().
Adopting the convention will raises another issue: distinct
objects can compare as equal, so the DeHeap2 operations that
find items by value will be at least under-defined, and maybe
even broken. There are several ways to solve the problem, and
I don't know of Python convention as to which to choose.
