] | Calling the *function* `collections.namedtuple` gives you a new type that's a subclass of `tuple` (and no other classes) with a member named `_fields` that's a tuple whose items are all strings. So you could check for each and every one of these things:

t = type(x)
b = t.__base... | Improving on what Lutz posted:

isinstance(x, tuple) and isinstance(x.__dict__, collections.abc.Mapping)

which to me appears to best reflect the dictionary aspect of the nature of named tuples.
It appears robust against some conceivable future changes too and might also work with many third-party namedtuple-ish classes, if such thing... |

] | If you want to determine whether an object is an instance of a specific namedtuple, you can do this:
```
from collections import namedtuple
SomeThing = namedtuple('SomeThing', 'prop another_prop')
SomeOtherThing = namedtuple('SomeOtherThing', 'prop still_another_prop')
a = SomeThing(1, 2)
isinstance(a, SomeThing) ... | Improving on what Lutz posted:
