Track 8 · Lesson 9 of 11

Missing, empty and broken files

Handle files that are missing, empty, malformed or in an unexpected encoding, so one bad input does not stop the whole program.

You will be able to

• Catch FileNotFoundError with a small try/except and fall back to a sensible default
• Recognise completely empty and header-only files and treat them correctly
• Skip and count rows whose values cannot be converted, instead of crashing
• Recover from broken JSON and from files saved in a legacy encoding
