Description:

kitoolz 0.1.2

A set of utility functions for iterators, functions, and dictionaries.
See the PyToolz documentation at https://toolz.readthedocs.io

Install
toolz is on the Python Package Index (PyPI):
pip install toolz

Structure and Heritage
toolz is implemented in three parts:
itertoolz, for operations on iterables. Examples: groupby,
unique, interpose,
functoolz, for higher-order functions. Examples: memoize,
curry, compose,
dicttoolz, for operations on dictionaries. Examples: assoc,
update-in, merge.
These functions come from the legacy of functional languages for list
processing. They interoperate well to accomplish common complex tasks.

Example
This builds a standard wordcount function from pieces within toolz:
>>> def stem(word):
... """ Stem word to primitive form """
... return word.lower().rstrip(",.!:;'-\"").lstrip("'\"")

>>> from toolz import compose, frequencies, partial
>>> from toolz.curried import map
>>> wordcount = compose(frequencies, map(stem), str.split)

>>> sentence = "This cat jumped over this other cat!"
>>> wordcount(sentence)
{'this': 2, 'cat': 2, 'jumped': 1, 'over': 1, 'other': 1}

Dependencies
toolz supports Python 3.5+ with a common codebase.
It is pure Python and requires no dependencies beyond the standard
library.
It is, in short, a lightweight dependency.

CyToolz
The toolz project has been reimplemented in Cython.
The cytoolz project is a drop-in replacement for the Pure Python
implementation.
See CyToolz GitHub Page for more
details.

Contributions Welcome
toolz aims to be a repository for utility functions, particularly
those that come from the functional programming and list processing
traditions. We welcome contributions that fall within this scope.
We also try to keep the API small to keep toolz manageable. The ideal
contribution is significantly different from existing functions and has
precedent in a few other functional systems.
Please take a look at our
issue page
for contribution ideas.
