How to enable/disable a rule in AWS EventBridge using Python/Boto3

Question

How can you enable/disable an Event Bridge rule that schedules a Lambda Function.

The longer term goal is to turn off the schedule on certain holidays, so my next task is to see if there are any good holiday/management libraries. The first task was just to see if I could enable/disable the Event Bridge rule from a python program.

I first took this line from an S3 test I had working:

s3_resource = boto3.resource('s3') 

and changed it to

resource = boto3.resource('events') 

It returned the following error: boto3.exceptions.ResourceNotExistsError: The 'events' resource does not exist. The available resources are:

• cloudformation
• cloudwatch
• dynamodb
• ec2
• glacier
• iam
• opsworks
• s3
• sns
• sqs

I used pip to upgrade my boto release 1.17.57.

pip install boto3 --upgrade -t . 
pip install botocore --upgrade -t . 

I installed locally so I can zip this to a Lambda function eventually. I had to change resource to client as the method.

import uuid
import boto3
import os
import pprint

client = boto3.client('events') 
action = "enable"
myRulename = 'PolygonIOAPIDataCollectorMarketHours'

if action == "enable":
    response = client.enable_rule(
        Name=myRulename
    )
else:
    response = client.disable_rule(
        Name=myRulename
    )

pprint.pprint(response)

The first run, I got a security error, and had to add a policy to the IAM user.

It returns:

{'ResponseMetadata': {'HTTPHeaders': {'content-length': '0',
                                      'content-type': 'application/x-amz-json-1.1',

                      'HTTPStatusCode': 200,
                      'RequestId': '6d1de8cc-1c82-4a7f-956a-ad33e6e8c899',
                      'RetryAttempts': 0}}
