Answer 1

Here is how I did it using python boto3.

from boto3 import client as boto3_client
from datetime import datetime
import json
lambda_client = boto3_client('lambda')
def lambda_handler(event, context):
    msg = {"key":"new_invocation", "at": datetime.now()}
    invoke_response = lambda_client.invoke(FunctionName="another_lambda_",
                                           InvocationType='Event',
                                           Payload=json.dumps(msg))
    print(invoke_response)
