How do I use namedtuples in Python?

How do I use namedtuples in Python?

Namedtuples 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 namedtuple?

Sure! Here's a simple example:

from collections import namedtuple

# Define a namedtuple 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 namedtuples?

Namedtuples provide better readability and self-documenting code. They also allow for immutability, which can help prevent accidental changes.

Can I convert a namedtuple to a dictionary?

Yes, you can convert a namedtuple to a dictionary using the _asdict() method. For example:

p_dict = p._asdict()
print(p_dict)  # Output: {'x': 10, 'y': 20}
