slinkie 0.1.5

A LINQ-esque project.

Introduction

This is an implementation of LINQ in Python.

Functions

• between(a, b, key=None): Returns items between a and b. (Inclusive).

• count(): Consumes all items to produce a count.

• dict(key=None, transform=None): Returns a dict of all items.

• exclude(items, key=None): Excludes all items based on either their identity, or a key function.

• extend(items): Yields all the items from this._items, followed by the items supplied to this function.

• filter(key): Filter the items.

• first(key=None): Take the first item if key is None, otherwise take the first item where key(item) returns true. If there are no objects, StopIteration is raised.

• first_or_none(key=None): Take the first item if key is None, otherwise take the first item where key(item) returns true. If there are no objects, None is returned.

• flatten(): Flatten a two-dimensional result set into a single dimension.

• group(key): Groups all items on key.

• join(glue=’’): Joins the items by glue, where glue is a string. Calls glue.join.

• last(key=None): Take the last item if key is None, otherwise take the first item where key(item) returns true. If there are no objects, StopIteration is raised.

• last_or_none(key=None): Take the first item if key is None, otherwise take the first item where key(item) returns true. If there are no objects, None is returned.

• len(): Consumes all items to produce a count.

• list(): Returns a list of all items.

• map(transform): Map the items.

• not_none(): Returns all items except None.

• partition(n): Takes n items and returns them in a new Slinkie. Does so until the items are consumed.

• select(transform): Map the items.

• set(): Returns a set of all items.

• skip(n): Skip n items.

• sort(key=None, reverse=False): Sorts the items by key.

• take(n): Take n items.

• tuple(): Returns a tuple of all items.

• where(key): Filter the items.

Installation

Slinkie is available on pip, so a simple “pip install slinkie” should do it.
