Named tuple

Immutable, like a tuple.

See namedtuple in the docs.

factory function for creating tuple subclasses with named fields

Example

from collections import namedtuple

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

# Instantiate using the type.
p = Point(11, y=22)

p
# => Point(x=11, y=22)

Access attributes with class-like attribute syntax.

p.x
# => 111
