Example for depaginating boto3 results from AWS.

aws-depaginate-boto.py

import boto3

def depaginate(function, resource_key, **kwargs):
    # Will depaginate results made to an aws client
    response = function(**kwargs)
    results = response[resource_key]
    while (response.get("NextToken", None) is not None):
        response = function(NextToken=response.get("NextToken"), **kwargs)
        results = results + response[resource_key]
    return results

# I created this because the boto3 client for AWS organizations has no paginators
client = boto3.client("organizations")
parent_obj = client.list_roots()['Roots'][0]

child_accounts = depaginate(
    function=client.list_accounts_for_parent,
    resource_key='Accounts',
    ParentId=parent_obj["Id"]
)
