How to Build Cursor Pagination with Next and Prev Tokens in Python
A minimal cursor pagination implementation that returns next and previous cursor tokens for navigating a dataset.
from pprint import pprint
def make_cursor(page):
return f"page:{page:04d}"
def parse_cursor(cursor):
_, page = cursor.split(":", 1)
return int(page)
def paginate(all_items, page_size, cursor=None):
start = parse_cursor(cursor) if cursor else 0
end = start + page_size
items = all_items[sta…How to Parse Multipart Form Data in Python
Parse multipart/form-data uploads using the Python standard library's cgi module to extract both regular fields and file uploads.
import cgi
from io import BytesIO
def parse_multipart_form(headers, body_bytes):
content_type = headers.get("Content-Type", "")
content_length = int(headers.get("Content-Length", len(body_bytes)))
# Create a file-like object from bytes for cgi.FieldStorage
body_file = BytesIO(body_bytes)
