Primitive Data Type

Primitive Data Type is a DSA topic. In plain words you use it for a short Primitive Data Type example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Primitive Data Type example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Primitive Data Type.

From the example next to this theory — Primitive Data Type: dry-run [4, 1, 3].

Trap — only saying “Primitive Data Type” with no example. Fix that before you talk about advanced DSA.

Viva — what is Primitive Data Type? Then show the smallest Primitive Data Type example you can type. Then name the trap.

Exam tip

What is Primitive Data Type? Show this: the smallest Primitive Data Type example you can type. Trap: only saying “Primitive Data Type” with no example.

Example

# Primitive Data Type
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)

Primitive Data Type: dry-run [4, 1, 3]. Say the list after one step.
