Appendix C. A brief introduction to type hints
Python introduced type hints (or type annotations) as an official part of the language through PEP 484 and Python version 3.5. Since then, type hints have become more common throughout many Python codebases, and the language has added more robust support for them. Type hints are used in every source code listing in this book. In this short appendix, I aim to introduce type hints, explain why they are useful, explain some of their problems, and link you to more in-depth resources about them.
Warning
This appendix is not meant to be comprehensive. Instead, it’s a brief kickstart. Please see the official Python documentation for details: https://docs.python.org/3/library/typing.html.
