These are part of the collections module and act very similar to regular tuples
The main difference being that values stored in a named tuple can be accessed using field names instead of indexes.
For example, a point in the two-dimensional plane can be represented using two coordinates. In a regular tuple, these values would be accessed by index ([0] and [1]), but if we define a named tuple, Point, we can access them using x and y instead (although we can still use indexes, too, if we want):
Example:
from collections import namedtuple
# Regular tuple p = (2, 4) # p[0] = 2, p[1] = 4
# Named tuple Point = namedtuple('Point', 'x y') q = Point(3, 5) # q.x = 3, q.y = 5
