How can I use namedtuple from the collections module in Python?

You can use namedtuple to create tuple subclasses with named fields, making your code more readable. Here's an example:

from collections import namedtuple

# Define a namedtuple
Point = namedtuple('Point', ['x', 'y'])

# Create an instance
p = Point(10, 20)

# Access fields
print(p.x, p.y)  # Output: 10 20

What are the advantages of using namedtuple over regular tuples?

Namedtuples provide more readability and self-documenting code since you can access fields by name instead of index. This reduces errors and makes your code easier to understand.

Can I add methods to a namedtuple?

Yes, you can subclass namedtuple 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

p = Point(3, 4)
print(p.distance())  # Output: 5.0
