logger = logging.getLogger(__name__)


class MyException(Exception):
        pass


@retry(stop=stop_after_attempt(3), wait=wait_fixed(1))
def raise_my_exception():
    raise MyException("Fail")


try:
    raise_my_exception()
    print("aiueo1")
except MyException:
    print("aiueo2")
except RetryError:
    print("aiueo3")  # output: aiueo3
