How do I use named tuples in Python?

Named tuples are a subclass of tuples that allow you to access fields by name instead of position. You can create one using the collections.namedtuple factory function.

Can you show me an example of how to create a named tuple?

Sure! Here's a simple example:

from collections import namedtuple

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

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

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

What are the advantages of using named tuples over regular tuples?

Named tuples provide better readability and self-documenting code since you can access elements by name. They also allow for more meaningful code.

Can named tuples be modified after creation?

No, named tuples are immutable, just like regular tuples. Once created, you cannot change their values.
