Better way write custom filters | Python - AWS - Boto3

My requirement is to filter based on 2 conditions:

  1. Stopped instances
  2. Instances with certain tag

I can achieve this by writing 2 separate custom filters, but I want to know if I can achieve the same in single filter.

My Code:

    stopped_filter = Filters=[{'Name': 'instance-state-name', 'Values': ['stopped']}]
    stopped_instances = ec2.instances.filter(Filters=stopped_filter)

    tag_filter = Filters=[{'Name':'tag-key', 'Values':['doaf']}]
    tagged_instances = ec2.instances.filter(Filters=tag_filter)

What I have tried:

    filter = Filters=[{'Name': 'instance-state-name', 'Values': ['stopped']}, {'Name':'tag-key', 'Values':['doaf']}]
    stopped_and_tagged_instances = ec2.instances.filter(Filters=filter)

This line:

filter = Filters=[{'Name': 'instance-state-name', 'Values': ['stopped']}, {'Name':'tag-key', 'Values':['doaf']}]

Should be:

filter = [{'Name': 'instance-state-name', 'Values': ['stopped']}, {'Name':'tag-key', 'Values':['doaf']}]

Full example:

import boto3

ec2 = boto3.resource('ec2', region_name='ap-southeast-2')
filter = [{'Name': 'instance-state-name', 'Values': ['stopped']}, {'Name':'tag-key', 'Values':['Foo']}]
stopped_and_tagged_instances = ec2.instances.filter(Filters=filter)
print([i.id for i in stopped_and_tagged_instances])
