10.12 Named Tuples

You’ve used tuples to aggregate several data attributes into a single object. The Python Standard Library’s collections module also provides named tuples that enable you to reference a tuple’s members by name rather than by index number.

Let’s create a simple named tuple that might be used to represent a card in a deck of cards. First, import function namedtuple:

We now have a new tuple type named ...
