instance_type = 't2.micro' # https://aws.amazon.com/tw/ec2/instance-types/

                    MinCount=1, 
                    MaxCount=1,
                    InstanceType=instance_type,
                    )

Stop Instances

import boto3

client = boto3.client('ec2','ap-northeast-3')

instance_id = "i-0c1cfc6b6eb28e993"
response = client.stop_instances(
    InstanceIds = [instance_id],
    Force = True
)

print(response)

import boto3

client = boto3.client('ec2','ap-northeast-3')

instance_id = "i-0c1cfc6b6eb28e993"
