categories: Types,Exception

description: All exceptions have readable ``value`` and ``errno`` attributes, not just ``StopIteration`` and ``OSError``.

cause: MicroPython is optimised to reduce code size.

workaround: Only use ``value`` on ``StopIteration`` exceptions, and ``errno`` on ``OSError`` exceptions. Do not use or rely on these attributes on other exceptions.
