How to Paginate a List with a Generator in Python
Define a generator that yields list items in fixed-size pages, simulating pagination for cloud resource APIs.
from typing import List, Iterator
def paginate_generator(items: List[str], page_size: int = 3) -> Iterator[List[str]]:
"""Yield items in fixed-size chunks with a mock pagination pattern."""
for i in range(0, len(items), page_size):
yield items[i:i + page_size]
if __name__ == "__main__":
resources…Mock S3 List Objects Paginator in Python
This code implements a mock S3 paginator that yields pages of object keys, mimicking the behavior of boto3's list_objects_v2 paginator for local testing.
import json
from datetime import datetime, timezone
class MockS3Paginator:
"""A mock S3 list_objects_v2 paginator returning pages of keys."""
def __init__(self, bucket, all_keys, page_size=1000):
self.bucket = bucket
self.all_keys = all_keys
self.page_size = page_size
