Exceptions that may occur when you use Alibaba Cloud Darabonba SDK for Python are classified into the following types:

1. UnretryableException: This type of exception is caused by network issues. TeaUnretryableException is thrown if the number of retries reaches the upper limit.

2. TeaException: This type of exception is caused by business errors. The following three parameters are provided to handle this type of exception:

   code: the error code that is returned when the exception occurs.

   message: the error message that is returned when the exception occurs. The message contains the ID of the API request for which the exception is thrown.

   data: the detailed error information that is returned by the server for the exception.
