I guess I could duck-type it based on the fields attribute but that feels implicit and fragile.

What do you guys suggest? I seem to remember a previous discussion that concluded that duck typing based on fields was the way to go. (It's a public API, despite the , due to name-tuple's attribute namespacing issues.)

Yes. That is the recommended approach.

IIRC that was Guido's suggestion rather than creating an abstract base class for a named tuple (any tuple-like class with indexable elements that are also accessible using named attributes).
