I am wondering if in Python exists a data structure for which is possible induce a custom internal ordering policy. I am aware of OrderedDict and whatnot, but they do not provide explicity what I am asking for. For example, OrderedDict just guarantees insertion order.
I really would like something that in C++ is provided with the use of comparison object: for example in std::set<Type,Compare,Allocator>, Compare is a parameter that define the internal ordering of the data structure. Usually, or probably always, it is a binary predicate that is evaluate for a pair of elements beloning to the data structure.
Is there something similar in Python? Do you know any workaround?
