Read an Exception Message Safely

Easy ⏱ 8 min 80% acceptance ★★★★★ 4.6

Write error_text(func) that calls the zero-argument func() and returns the string 'ok' on success, or f'failed: {err}' when it raises — where err is the caught exception converted to its message text via str(). Practice binding the exception with as and using its printable form.

Examples

Example 1

Input

error_text(lambda: int('xyz'))

Output

"failed: invalid literal for int() with base 10: 'xyz'"

Explanation

str(err) yields the human-readable message.

Constraints

Catch Exception, bind it with as.
Success returns exactly 'ok'.
