There is also PEP 487[2], which means you can do more without needing a metaclass. 1. https://docs.python.org/3/library/typing.html#typing.NamedTuple https://docs.python.org/3/library/typing.html#typing.NamedTu... 2. https://www.python.org/dev/peps/pep-0487/ https://www.python.org/dev/peps/pep-0487/
