python3-immutabledict binary package in Ubuntu Noble riscv64

 Immutabledict implements the complete mapping interface and can be
 used as a drop-in replacement for dictionaries where immutability is
 desired. The immutabledict constructor mimics dict, and all of the
 expected interfaces (iter, len, repr, hash, getitem) are provided. Note
 that an immutabledict does not guarantee the immutability of its values,
 so the utility of hash method is restricted by usage.
 .
 The only difference is that the copy() method of immutable takes variable
 keyword arguments, which will be present as key/value pairs in the new,
 immutable copy.
