FOSS4G 2023 Prizren

Static type hints according to PEP 484 (and its extensions) have been a part of Python since version 3.5, which came out in 2015. Research from 2021 shows that 3 out of 4 Python developers already use optional type hinting at least sometimes in their projects. Time is ripe for static type hints to enter the FOSS4G Python world!

This talk will give an overview on the current status of the effort to add type hints to fiona. Furthermore it will briefly discuss considerations and the reasoning behind design decisions taken up until then. Contributions to the effort are very much welcome – just take part in the discussion on GitHub.
