Step 9: Resilience against network failures

What you gain

You learn to retry: retry(func, retries=7, description=None) repeats a call that raises, waits between attempts, logs a warning and raises RetriesExhaustedError at the end. login(), book_class() and get_my_bookings() are wrapped with it, so a site that drops requests does not stop the run.

Screenshot

This screenshot needs a run with a real gym account. The maintainer adds it with --screenshot-dir (see Getting started); until then the file docs/images/step-9.png is missing and the image above does not show.
