Get more than 10 results from ec2 get_spot_placement_scores

Describe the bug

I want to get more than 10 results from get_spot_placement_scores method, but it returns maximum 10 results. Is there any way to get more than 10 results? I checked this method can take “NextToken” parameter, but there’s no “NextToken” from the response… Is this limited to use? or do I have some mistake?

Steps to reproduce

import boto3

session = boto3.session.Session(profile_name='dev')
ec2 = session.client('ec2', region_name='us-west-2')

response = ec2.get_spot_placement_scores(
    InstanceTypes=['g3s.xlarge'],
    TargetCapacity=1,
    SingleAvailabilityZone=True
)

print(response)
print(len(response['SpotPlacementScores']))

Expected behavior I want to get “NextToken” string from the response, and want to get more than 10 results from single request Thank you for helping me.

Hi @odobenuskr,

Thanks for your question. The operation GetSpotPlacementScores is paginated and by default returns 10 items at a time. You’ll need to use a paginator to help you continue making subsequent requests. You’ll need to do something like the following:

import boto3

session = boto3.session.Session(profile_name='dev')
ec2 = session.client('ec2', region_name='us-west-2')

# Create a reusable Paginator
paginator = ec2.get_paginator('get_spot_placement_scores')

page_iterator = paginator.paginate(
    InstanceTypes=['g3s.xlarge'],
    TargetCapacity=1,
    SingleAvailabilityZone=True
)

for page in page_iterator:
    print(page['Contents'])

Thank you for checking this problem, @kdaily !

I think this API response is limited by AWS, so I will try another way.

Thank you for helping me!
