Tuples & When to Use Them

Tuples — Immutable Sequences

A tuple is like a list but immutable — once created, it cannot be changed. Use tuples for data that should not be modified.

coordinates = (40.7128, -74.0060)  # New York lat/lon
rgb_red = (255, 0, 0)

List vs Tuple — When to Use Which?

Tuple Unpacking

One of Python's most elegant features:

point = (10, 20)
x, y = point  # x=10, y=20

# Swap variables without temp
a, b = 5, 10
a, b = b, a   # a=10, b=5

Named Tuples

For readability, use collections.namedtuple:

from collections import namedtuple
Point = namedtuple("Point", ["x", "y"])
p = Point(10, 20)
print(p.x, p.y)  # 10 20
