This typing utility provides static typing classes that can be used to ease the development by providing the IDE type hints.
- Add static typing classes
- Ease the development by leveraging your IDE's type hints
- Avoid common typing mistakes in Python
???+ tip All examples shared in this documentation are available within the project repository{target="_blank"}.
We provide static typing for any context methods or properties implemented by Lambda context object{target="_blank"}.
The LambdaContext typing is typically used in the handler method for the Lambda function.

```
Using LambdaContext typing makes it possible to access information and hints of all properties and methods implemented by Lambda context object.
