Python 
from collections import namedtuple, asdict

def main():
    # Define a namedtuple for a person
    Person = namedtuple("Person", ["name", "age", "city"])
    person = Person(name="Alice", age=30, city="New York")

How to Use NamedTuples for Lightweight Records in Python

Create lightweight, immutable data records with namedtuple that behave like tuples but have named fields for improved readability and access.

namedtuple tuples records
Python 
from collections import namedtuple

Point = namedtuple("Point", ["x", "y"])

p = Point(3, 4)
print(p)
print(p.x, p.y)
print(p[0], p[1])

x, y = p
print(x, y)

print(p._asdict())

p2 = p._replace(x=10)
print(p2)

if __name__ == "__main__":
    print("NamedTuple demo complete")

NamedTuple typed record in Python

Define a lightweight immutable record with type hints using typing.NamedTuple; access fields by name and unpack like a tuple.

namedtuple typing records
Python 
from typing import NamedTuple


class Point(NamedTuple):
    x: float
    y: float
    label: str = "origin"


if __name__ == "__main__":
    p = Point(3.5, -2.0, "A")
    print(p)
    print(f"x={p.x}, y={p.y}, label={p.label}")
    print("is tuple:", isinstance(p, tuple))

    q = Point(1.0, 1.0)
    print(q)
