Which Python data structure is immutable

Which Python data structure is immutable is a DSA topic. In plain words you use it for a short Which Python data structure is immutable example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Which Python data structure is immutable example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Which Python data structure is immutable.

From the example next to this theory — Which Python data structure is immutable: dry-run [4, 1, 3].

Trap: only saying “Which Python data structure is immutable” with no example. Fix that before you talk about advanced DSA.

Viva: what is Which Python data structure is immutable? Then show the smallest Which Python data structure is immutable example you can type. Then name the trap.

Exam tip

What is Which Python data structure is immutable? Show this: the smallest Which Python data structure is immutable example you can type. Trap: only saying “Which Python data structure is immutable” with no example.

Example

# Which Python data structure is immutable
data = [4, 1, 3]
print("start", data)
if data[0] > data[1]:
    data[0], data[1] = data[1], data[0]
print("after one step", data)

Which Python data structure is immutable: dry-run [4, 1, 3]. Say the list after one step.
