Classes

class LambdaContext

The LambdaContext static object can be used to ease the development by providing the IDE type hints.

Example

A Lambda function using LambdaContext

>>> from typing import Any, Dict
>>> from aws_lambda_powertools.utilities.typing import LambdaContext
>>>
>>> def handler(event: Dict[str, Any], context: LambdaContext) -> Dict[str, Any]:
>>>     # Insert business logic
>>>     return event
