Call an operation up to attempts times and return a result dictionary containing ok, value or error, and attempts_used. Do not retry KeyboardInterrupt or SystemExit.
Write down the input contract and the failure cases before coding.

A retry helper is a boundary between unreliable work and its caller. Catching Exception leaves process-control exceptions alone, while the stable result shape lets UI or command-line code report success and failure without inspecting exception types.
your-solution.py.solution.py only after a real attempt.This advanced Python exercise focuses on Exceptions, Retry policies, API contracts. Its requirements define the exact behavior to implement before you write code.
Open your-solution.py and select Run code. The browser loads Python in an isolated worker and runs your function against the visible tests.
Attempt Model a retry result contract first. Then open the read-only solution file to compare the contract, edge-case handling, and implementation choices—not simply to copy the final code.
