Episodes run on a tablet or larger screen.

The situation

A creator challenge produces a comment export far larger than yesterday's demo file. The old script processed 40 rows by hand-unrolling them. That is not going to work today.

What you'll learn

  • PCEP 2.2 and 3.1: for and while loops, range, break / continue / pass, the loop-else clause, nested loops, and basic list traversal.

Who you work with

  • Maya Chen

    Senior AI Engineer · Your mentor

  • Jax Rivera

    Creator Partnerships Lead

Scenes

  1. 1.Too big to unroll
  2. 2.Find the off-by-one
  3. 3.Count per creator
  4. 4.Empty batch, or interrupted?
  5. 5.Loops check

What you leave with

You counted comments per creator with a loop that skips bad rows instead of dying on them, and you can tell an empty batch from an interrupted one — which is what the retry logic actually needs.
