Exercise: Recover Ticket Counts

A ticket spreadsheet sometimes contains "many" instead of digits. The prior demo caught a specific conversion failure; now use it for a different function. IndexError from a bad list index or NameError from a typo would not be fixed by catching ValueError, so do not use a bare except.

Edit main.py, Run to compare both sample labels, then Submit. The starter supplies the labels; each helper is independently testable.

Your Task

  1. Complete ticket_count(text) to return int(text) for valid integer text and 0 for text that raises ValueError, using try/except ValueError.
  2. Complete ticket_label(text) to return "Tickets: <count>" using ticket_count(text).
