There are decorators with "include"  and "included" in this SO Q&A:

The same strategies applied by the decorators may be applied by a by a
function called from within __init__.

For the cases I've found in which classes define several attributes that
are initialized in the constructor I think that a library like
https://github.com/python-attrs/attrs does what's needed. The downside is
that code-writing tools (like IDEs) don't understand what's going on under
the hood.
