NamedTuple assign meaning to each position in a tuple and allow for more readable, self-documenting code. They can be used wherever regular tuples are used, and they add the ability to access fields by name instead of position index. Namedtuples are created using the collections.namedtuple() factory function.

Namedtuples offer several advantages over tuples:

• The values of namedtuples cannot be changed after they have been created because they are immutable.
• Namedtuples are hashable, which means they can be used as dictionary keys.
• A namedtuple is comparable, which means that it can be sorted and compared with other namedtuples.
