Functional programming core library for Python.

fncore

A collection of functional programming for Python.

Quickstart

$ pip install fncore
$ python3

>>> from fncore import *
>>> xs = [1,2,3]
>>> reduce(fn.operator.add, xs)
6

Background

fncore was written to make the tools necessary for functional programming in Python easier to acces. By design, these tools are scattered across other modules: the built-ins functools, itertools and operator and the community-managed toolz and more-itertools. fncore collects the code from these sources and wraps them in a single namespace for easy access.

Use

Use of fncore is as simple as pip installing fncore and then importing the package. It is recommended that you * import fncore, even though this goes against Python conventions.

from fncore import *

Importing fncore in this way will bring some commonly used functions into your default namespace:

• functools.reduce
• functools.partial
• toolz.functoolz.curry
• toolz.dicttoolz.merge
• toolz.dicttoolz.merge_with

And the functional-support code will be stored under the fn namespace.
