How do I create namedtuples in Python?

You can create a namedtuple by using the collections.namedtuple function. Here's an example:

from collections import namedtuple

Point = namedtuple('Point', ['x', 'y'])
point = Point(10, 20)
print(point.x, point.y)  # Output: 10 20

What are the advantages of using namedtuples?

Namedtuples provide a way to create lightweight, immutable objects that are more readable than regular tuples. They allow you to access fields by name instead of index, which improves code clarity.

Can I add methods to namedtuples?

Namedtuples are immutable and don't support adding methods directly. However, you can subclass them to add methods. Here's an example:

class Point(namedtuple('Point', ['x', 'y'])):
    def distance(self):
        return (self.x**2 + self.y**2)**0.5

Are namedtuples memory efficient?

Yes, namedtuples are more memory efficient than regular classes because they do not have per-instance dictionaries. They use a fixed-size structure.
