Details on the AWS Lambda Python LambdaContext context object when instantiated from a CloudFormation stack

LambdaContext

Hi Gene –

Thanks for the gist. I've seen examples of people calling context.succeed() in the Node.js runtime. Is this possible with Python? I can't find anything in the docs.

Thanks for the gist :)
I have the exact same problem. Can't find anything in the docs about the said succeed or done methods that seem to be used with Node.js runtime.

Hi Michael and Gene,
I'm running into the same problem. Did either of you find a workaround to exit the program early without throwing an error?

@msambol @Depado @cameck have you tried just returning from the handler function?
