In all the years I've used and taught namedtuples, I think I've never used the ._replace() method. The leading underscore is a hint that the method is "private"
Usually that would be true, but namedtuple is a special case. The docs make it clear that the underscore is there to prevent it from clashing with a potential field name, not to suggest privateness.
OK, that's a good point. I kinda hadn't thought about that fact. But nonetheless, I haven't been shy to use ._asdict(), so I wasn't avoiding ._replace() out of concerns for a "private" declaration. It's just not a thing I've needed. Which makes me feel like having a way to spell it that is a few characters shorter is not an important life concern for me. :-)
