Type hints

Python has support for type hints (or type annotations) that allow users to provide information on the type of variables.

Type hints can be used

• by editors to provide better introspection into objects.

• by tools like mypy that check your code given the variable types.

• as additional documentation.

pytask uses type hints as part of its interface.
