AWS Lambda function that deletes itself

aws_lambda_self_destruct.py

import os
import boto3

lclient = boto3.client ('lambda')
print ('function loaded')

def lambda_handler(event, context):
    lclient.delete_function (FunctionName = context.function_name)
    print ('I am deleted')
    return True

Does this actually work?
I always wondered if this could work.
I assume this means you would have to give that function's role the permission to delete itself?

[Update]
I can confirm this DOES work.
You do need to give that function's role permission to delete itself.
