Modules in Python: namedtuple
Let's discover namedtuple and its functions.
We'll cover the following...
Overview of namedtuple
Let’s discuss the namedtuple class from the collection module which we can use to replace Python’s tuple.
Of course, the namedtuple is not a drop-in replacement as we will see soon.

from collections import namedtupleParts = namedtuple("Parts", "id_num desc cost amount")auto_parts = Parts(id_num="1234", desc="Ford Engine", cost=1200.00, amount=10)print(auto_parts.id_num)
Here we import namedtuple from the ...
