Lambda Function

gistfile1.txt

import boto3
#This simple lambda function is available from AWS with instructions on starting and stopping an instance at regular intervals using Lambda and CloudWatch: https://aws.amazon.com/premiumsupport/knowledge-center/start-stop-lambda-cloudwatch/
# Enter the region your instances are in. Include only the region without specifying Availability Zone; e.g., 'us-east-1'
region = 'us-east-1'
# Enter your instances here: ex. ['X-XXXXXXXX'] you can comma separate the instance IDs for more than one instance: i.e. ['X-XXXXXXXXX', 'X-XXXXXXXXX"]
instances = ['i-0902effe70a087ae7']

def lambda_handler(event, context):
    ec2 = boto3.client('ec2', region_name=region)
    ec2.stop_instances(InstanceIds=instances)

can we pull multiple instance id's from lambda environment variables ?
