Have you used third-party libraries for implementing pagination?

Yes, for implementing pagination in Python, third-party libraries are often used, especially when working with web frameworks or ORM.

For example, Django has a built-in Paginator class:

from django.core.paginator import Paginator

items = ['a', 'b', 'c', 'd', 'e']
paginator = Paginator(items, 2)  # 2 items per page

page1 = paginator.page(1)
print(page1.object_list)  # ['a', 'b']

Libraries for APIs are also popular, for example, django-rest-framework provides powerful pagination tools.

In other cases, libraries like paginate can be used, or pagination can be implemented manually using list slices or LIMIT and OFFSET parameters in SQL queries.
