Named Tuples

Tuples with named fields, from the collections module. See namedtuple — Python docs.

Why use them?

Regular tuples require remembering what each index means — point[0] vs point.x. Named tuples give you readable field access while keeping the lightweight, immutable nature of a tuple.

Point2d = namedtuple('Point2d', 'x y')
p = Point2d(10, 20)
print(p.x)    # 10  — by name
print(p[0])   # 10  — by index still works
