How is access to elements of namedtuple in Python implemented?

Accessing elements of a namedtuple in Python is done by field name or by index.

By field name:

// Creating a namedtuple
from collections import namedtuple
Point = namedtuple('Point', ['x', 'y'])
p = Point(10, 20)

// Accessing elements by name
x_coord = p.x
y_coord = p.y

By index:

// Creating a namedtuple (using the same 'Point' namedtuple from the previous example)
// from collections import namedtuple
// Point = namedtuple('Point', ['x', 'y'])
// p = Point(10, 20)

// Accessing elements by index
x_coord = p[0]
y_coord = p[1]

When iterating:

// Creating a namedtuple (using the same 'Point' namedtuple from the previous example)
// from collections import namedtuple
// Point = namedtuple('Point', ['x', 'y'])
// p = Point(10, 20)

// Iterating over elements
for value in p:
    print(value)
