More correctly, some Python data types are immutable leaving the
only method of internal manipulation the creation of new objects of
that type with the requisite data contents. Strings and tuples, for
instance, are immutable under Python, but lists and dictionaries are
quite definitely mutable.
Happily enough from a syntactical PoV, the syntax for immutable and
mutable objects, is identical, and the handling of references,
object copies, etc, is also quite transparent.

Given that heaps are generally implemented as lists or dictionaries
(out of the catalog of basic Python types), and that both are
mutable, this is not a problem
