How do you define and access a FastAPI path parameter?

Tests FastAPI route-to-function binding. Good answer: curly-brace syntax in the decorator path, a matching typed function argument, and awareness that FastAPI auto-extracts and converts the value.
Tests FastAPI declarative routing and auto-extraction. Strong answer: format-string syntax in the decorator like app.get("/users/{user_id}"), a matching typed function argument like user_id as int, and the fact that FastAPI converts and injects the value automatically. Red flags: manually parsing the request object, omitting type hints, or renaming the argument without Path().
