Lesson 22 — Custom exceptions
Your own errors
Define a class that inherits from Exception to signal a specific problem, then raise it with raise MyError("message").
Why it matters: clear error types make programs easier to debug and control.
Make check() raise TooSmall when n < 10; the except block then prints the message.
Run your code — when the output matches the task, you will see a green check. Then mark the lesson complete.
