Named tuple

Named Tuples

syntax

from collections import namedtuple
Point = namedtuple('Point', ['x', 'y'])

example

from collections import namedtuple

Color = namedtuple("Color", ["red", "green", "blue"])
sky = Color(135, 206, 235)
print(sky.red, sky.blue)
print(sky._asdict())

output

135 235
{'red': 135, 'green': 206, 'blue': 235}

Note Named tuples give readable field access while staying immutable. For mutable fields or defaults, consider dataclasses instead.

Arrays & Tuples

TS · Basic Types

syntax

let arr: Type[] = [...];
let arr: Array<Type> = [...];
let tup: [TypeA, TypeB] = [a, b];

example

let scores: number[] = [95, 87, 72];
let names: Array<string> = ["Alice", "Bob"];

// Tuple — fixed length, positional types
let userRecord: [string, number, boolean] = ["alice", 30, true];

// Named tuple elements (TS 4.0+)
let range: [start: number, end: number] = [0, 100];

output

// userRecord[0] is string, userRecord[1] is number, userRecord[2] is boolean

Note Type[] and Array<Type> are identical. Tuples enforce length and per-position types at compile time, but at runtime they are just arrays — push() can still add elements unless you mark the tuple as readonly.
