Five more tools this week. make_update_line, summarize_plan, parse_customer_csv, load_customers_from_csv, customers_to_json. Which one unlocked the most?
Honestly load_customers_from_csv. The moment I realised io.StringIO turns a string into a fake file — so csv.DictReader just works without touching the filesystem — that was the click.
That pattern is everywhere in Python. StringIO, BytesIO — whenever a library expects a file, you can hand it a string or bytes in memory. It's the foundation of clean, testable code.
And customers_to_json means my entire Monday workflow is now: load CSV → compute summary → export JSON → paste into Slack. Four function calls.
Your Slack bot just became automated. That's Week 4 energy arriving a week early.
Two of these questions reach back into Week 1 and Week 2. Let's see if they held.
Six questions, all from the last three weeks. You've built half the capstone already.
