Five functions, all connecting to the pipeline you started in Week 1. Which one felt most different from what you expected?
load_clients_from_csv with io.StringIO. I expected file reading to involve opening a file path. A fake-file wrapper for a string feels like a workaround.
It is a design choice, not a workaround. The function signature takes a string — testable, composable, and identical whether the string came from disk, an API, or your time-tracker export. The StringIO wrapper is the adapter between string and file interface.
clients_to_json was the most satisfying. The round-trip test — dumps, loads, verify — made the output feel solid. Not just a formatted string; an actually validated JSON blob.
That instinct for verification is worth more than any single function. Let's see what the full three weeks have built.
Ready. Six questions from the full pipeline.
Two from Weeks 1 and 2 to keep those patterns warm.
