from types import SimpleNamespace

ns = SimpleNamespace(a=1)
ns.update(b=2)
print(ns)  # namespace(a=1, b=2)

Why?
Improves usability by providing an intuitive way to update attributes

Avoids reliance on internal .__dict__ access

Matches expectations from dict.update()

Implementation Notes
Implemented in C (Objects/namespaceobject.c)

Uses PyDict_Update(self->__dict__, kwargs)

Supports inspect.signature() via __text_signature__

Unit test added to test_types.py
