Python-AWS-Dataclasses provides data-classes for AWS lambda events and other AWS data. The dataclasses are type-annotated, as to allow for full IDE (code completion / IntelliSense) support.

# using pip
pip install python-aws-dataclasses
# or using pipenv
pipenv install python-aws-dataclasses.git

Assuming you have a dict of some AWS event (e.g. events passed into your lambda_handler) use the from_event()-method and access the objects via the dot-notation.

def lambda_handler(event, context):
  # Example 1: Lambda asynchronously invoked via SNS
  sns_event = SnsEvent.from_event(event)
  print(sns_event.first_record.sns.message)
  # Example 2: Lambda asynchronously invoked via S3-Event
  s3_event = S3Event.from_event(event)
  print(s3_event.first_record.s3.bucket.name)
