pyfuncol
A Python functional collections library. It extends collections built-in types with useful methods to write functional Python code. It uses Forbidden Fruit under the hood.
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]
{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}
