Motivation and Context

Distributing and packaging type information as per PEP 561 makes type checkers like mypy aware that the third-party package (in this case, Kedro) supports typing, and the importing package can then perform (Kedro-)typing-aware checking. The best alternative is to push stubs to typeshed, but that doesn't take full advantage of inline typing and is maintained by a different team.

How has this been tested?
