What you end up with
A retry policy that gets all 100 users through after an outage with 6.4 requests each. A table of which failures may be resent and which may not, a deadline per try and one overall, a way of calling a payment that charges only once however often it retries, and a fetchWithRetry you can use with the real fetch.

Starting from a single orders CSV, you narrow down where sales are falling, working from the whole to the breakdown to one candidate. Using nothing but pandas aggregation, you finish with a one-page report holding a conclusion, its evidence, what the data cannot tell you, and one next step.
You build a pricing table of three plans that holds its shape from a 360px phone up to a wide screen. The aim is to let it wrap because the content is cramped, without writing a single @media rule.
You take a function that does not match its spec and fix it by writing a failing test first rather than diving in. You learn how to pick the boundaries, and what to leave behind once it is fixed.
