I have written Python since 2003 and used walrus only once. It's unnecessary.

  Eh, I write a lot of Python and while it's unnecessary, it can make code easier to read if not overused. if (config_fn := base_dir / "config").exists(): ... is just a tiny bit shorter than this: config_fn = base_dir / "config" if config_fn.exists(): ... but if you do this enough times (if you are handling a lot of possible errors / missing data, etc.) it can definitely shorten the code.

    If you have to wrap it in parens, it might be shorter but it's not really clearer. In other contexts, parens are a good indication it's time for a new line. But I can agree something like this does look clean and clear: if value := obj.get("key"): ...
