4. Add decorators ATryExcept and ARetry, replacing TryExceptAsync and RetryAsync, respectively.
5. For the decorator TryExceptAsync and RetryAsync that will be deprecated, a large number of parameter comments are omitted.
6. Adjust the code block that gets logger in TryExcept.
7. Update the annotation information for the __getattr__ method, now the feature description is more complete.
8. Correct the description when the parameter error of the Retry.
