What is a namedtuple in Python and how does it ensure immutability?

A namedtuple is a subclass of Python's tuple that allows you to define a tuple with named fields. It ensures immutability by preventing changes to its fields after creation.

Can you give me an example of how to create a namedtuple?

Sure! You can create a namedtuple like this:

from collections import namedtuple

Point = namedtuple('Point', ['x', 'y'])
point = Point(10, 20)

What happens if I try to change a value in a namedtuple?

If you try to change a value in a namedtuple, you'll get an AttributeError. Namedtuples are immutable, so their fields cannot be modified.

Are there any advantages to using namedtuples over regular tuples?

Yes, namedtuples provide better readability and self-documenting code since you can access fields by name instead of index.
