Getting Started¶

Installation¶

pip install capo-comprehendmedical

Usage¶

from capo_comprehendmedical import AsyncComprehendMedicalClient


async def main():
    async with AsyncComprehendMedicalClient() as comprehend_medical:
        # Example: call the describe_entities_detection_v2_job operation
        response = await comprehend_medical.describe_entities_detection_v2_job()
        print(response["comprehend_medical_async_job_properties"])

Error Handling¶

The SDK raises exceptions for errors returned by the API. Catch them to handle failures gracefully.

from capo_comprehendmedical import AsyncComprehendMedicalClient
from capo_comprehendmedical.error import InternalServerException


async def main():
    async with AsyncComprehendMedicalClient() as comprehend_medical:
        try:
            await comprehend_medical.describe_entities_detection_v2_job()
        except InternalServerException as e:
            print(f"Error: {e}")
            print(e.data)  # additional error data

Retrying¶

The SDK retries failed operations automatically. Retry behaviour follows the Smithy specification: errors are retried based on their is_retryable and is_throttling_error attributes. Throttling errors use a longer base delay. Network-level failures (connection errors and timeouts) are also retried. Non-retryable errors, such as client errors without the @retryable trait, are raised immediately without further attempts.

The number of attempts defaults to 3 and can be changed at the client level via retry_max_attempts, or per call via config_overrides.

from capo_comprehendmedical import AsyncComprehendMedicalClient


async def main():
    async with AsyncComprehendMedicalClient() as comprehend_medical:
        # Default: 3 attempts for every operation
        response = await comprehend_medical.describe_entities_detection_v2_job()

        # Override per operation
        response = await comprehend_medical.describe_entities_detection_v2_job(config_overrides={"retry_max_attempts": 5})

        # Disable retries for this call
        response = await comprehend_medical.describe_entities_detection_v2_job(config_overrides={"retry_max_attempts": 1})
