Instead of nested Python containers, try using the @dataclass decorator to create small, behavior-less struct-like classes. You would have to create a name for the nested format anyway, so it may as well be a useful type. Apr 30, 2020 · Alas, the “almost” was a sticking point. In particular, PyCharm’s code insight only treated the built-in decorator as something providing dataclass support. A PyCharm plugin was needed, first to make PyCharm treat pydantic dataclasses like regular ones, then to fill in coding assistance for the other aspects.
