Snippet of providing parmeter values

provide_params.py

# if you wish to pass information about the triggering event as a parameter,
# simply add that to the inputs dictionary under the parameters key,
# whose value should be a dictionary of PARAMETER_NAME -> PARAMETER_VALUE

# pass the full event
inputs['parameters'] = dict(event=event)

# or just the bucket name
inputs['parameters'] = dict(bucket_name=event['Records'][0]['s3']['bucket']['name'])
