Functional collections extension functions for Python

pyfuncol

A Python functional collections library. It extends collections built-in types through Forbidden Fruit with useful methods to write functional Python code.

Installation

pip install pyfuncol

Usage

To use the methods, you just need to import pyfuncol. Some examples:

import pyfuncol

[1, 2, 3, 4].map(lambda x: x * 2).filter(lambda x: x > 4)
# [6, 8]

["abc", "def", "e"].group_by(lambda s: len(s))
# {3: ["abc", "def"], 1: ["e"]}

{"a": 1, "b": 2, "c": 3}.flat_map(lambda kv: {kv[0]: kv[1] ** 2})
# {"a": 1, "b": 4, "c": 9}

API

For lists: map, filter, flat_map, flatten, contains, distinct, foreach, group_by, is_empty, size, find, index_of.

For dictionaries: map, filter, flat_map, contains, foreach, is_empty, size, to_list.
