Validation Loops in Python

A useful prompt should recover when the first answer is not usable. This Block combines tools you already know—while True, input(), exception handling, condition checks, continue, and break—into one repeat-until-valid pattern.

What you will learn:

• Combine while True, try, and condition checks in one validation flow
• Retry after failed int() conversions by catching ValueError
• Choose a clear successful path with try/except/else or continue
• Check numeric ranges and validate normalized text choices
• Place break correctly and give useful feedback after rejected input

Leave with a practical flow you can reuse in interactive programs: ask, convert or normalize, check, explain, repeat, and continue only when the value is ready.
