README

        
``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

=============

``asq`` is available on the Python Package Index and can be installed with

easy_install from setuptools::

  $ easy_install asq

Alternatively you can download and unpack the source distribution (link to the

left) and install using::

  $ cd asq-1.0

  $ python setup.py install

Requirements

============

This version of ``asq`` works with Python 2.6 and higher, including Python 3.

It has been tested on Python 2.6, Python 2.7, Python 3.1 and Python 3.2.

Furthermore it is tested on !IronPython 2.6 and !IronPython 2.7.

``asq`` has a dependency on the ordereddict module which ships as standard

with Python 2.7 and upwards, but this module must be installed separately

for Python 2.6.
