asq 1.3

LINQ-for-objects style queries for Python iterables.

asq is simple implementation of a LINQ-inspired API for Python which operates over Python iterables, including a parallel version implemented in terms of the Python standard library multiprocessing module.

What It Does

asq is a package implementing queries over iterables of Python objects. asq provides a fluent interface making extensive use of method chaining to create complex queries without compromising readability. For example, to take the first five uppercased results from a list of words sorted by length and then alphabetically, try:

>>> from asq import query
>>> words = ["zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten"]
>>> query(words).order_by(len).then_by().take(5).select(str.upper).to_list()
['ONE', 'SIX', 'TEN', 'TWO', 'FIVE']

Over 40 standard query operators are provided together with various utilities to make the API even more convenient to use in Python.

How to get it
