zlinq

Python reimplementation of LINQ to Objects — lazy, chainable, fully typed query operators for iterables.

Install

uv add zlinq

or

pip install zlinq

Quick example

from zlinq import Enumerable

result = (Enumerable([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])
    .where(lambda x: x % 2 == 0)
    .select(lambda x: x * 10)
    .take(3)
    .to_list())

# [20, 40, 60]
