composetools

A library of utility functions for Pythonic function composition.
Most utilities are focused on transforming and dealing with iterables.

Install

pip install composetools

Functions

• compose

  Compose functions such that compose(f, g)(x) is equivalent to g(f(x))

• pipe

  Compose functions such that pipe(f, g)(x) is equivalent to f(g(x))

Utilities

• unique - Yield unique items of an iterable.
• each - Curried map.
• keep - Curried filter.
• mask - Curried itertools.compress.
• drop - Curried itertools.filterfalse.
• sort - Curried sorted.
• flat - Flatten an arbitrarily nested iterable to a desired depth.
