dill extends Python’s pickle module for serializing and de-serializing Python objects to the majority of the built-in Python types. Serialization is the process of converting an object to a byte stream, and the inverse of which is converting a byte stream back to a Python object hierarchy.

…

dill can pickle the following standard types:

    none, type, bool, int, float, complex, bytes, str,
    tuple, list, dict, file, buffer, builtin,
    Python classes, namedtuples, dataclasses, metaclasses,
    instances of classes,
    set, frozenset, array, functions, exceptions

dill can also pickle more ‘exotic’ standard types:

    functions with yields, nested functions, lambdas,
    cell, method, unboundmethod, module, code, methodwrapper,
    methoddescriptor, getsetdescriptor, memberdescriptor, wrapperdescriptor,
    dictproxy, slice, notimplemented, ellipsis, quit

cattrs: Flexible Object Serialization and Validation

Because validation belongs to the edges.

cattrs is a Swiss Army knife for (un)structuring and validating data in Python. In practice, that means it converts unstructured dictionaries into proper classes and back, while validating their contents.
Example

cattrs works best with attrs classes, and dataclasses where simple (un-)structuring works out of the box, even for nested data, without polluting your data model with serialization details:

Scriv is a command-line tool for helping developers maintain useful changelogs. It manages a directory of changelog fragments. It aggregates them into entries in a CHANGELOG file.

Make your functions return something meaningful, typed, and safe!
