What are namedtuples in Python and how are they immutable?

Can you explain what namedtuples are in Python?

Namedtuples are a subclass of tuples that allow you to access fields by name instead of position. They are defined using the collections.namedtuple factory function.

What does it mean that namedtuples are immutable?

Immutability means that once a namedtuple is created, its values cannot be changed. You can't modify, add, or remove fields.

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']); p = Point(10, 20).

How do I access the values in a namedtuple?

You can access the values using dot notation, like p.x for the x-coordinate and p.y for the y-coordinate.
