What are namedtuples in Python and why are they immutable?

Namedtuples are a subclass of tuples in Python that allow you to define simple classes for storing data. They are immutable, meaning once created, their values cannot be changed.

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

Sure! You can create a namedtuple using the collections.namedtuple function. For example:

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. For example:

point.x = 15  # This will raise an error

Why would I use namedtuples instead of regular tuples?

Namedtuples provide better readability and self-documenting code since you can access fields by name instead of index, making your code clearer.
