Lesson 5 — Loops

Repeating work

A for loop runs the same block once for each item in a sequence. range(5) produces 0, 1, 2, 3, 4 — note it stops before 5.

Why it matters: loops let you process a list of any size in a few lines instead of copying code over and over.

Tip: to count 1 to 10, use range(1, 11) — the start is included, the end is not.
