only-pipe 2.0.0

A non-intrusive Python pipeline.

Pipe.py

A non-intrusive Python pipeline.

There are only pipeline. If you want more functional tools, you should look for another library.

Install

pip install only-pipe

Or fetch from github

pip install git+https://github.com/abersheeran/only-pipe

Usage

Use pipeline to pass data as a positional parameter to the next function:

from pipe import F

range(10) | F(filter, lambda x: x % 2) | F(sum) == 25

Or you need to pass multiple parameters through the pipeline:

from pipe import FF


def get_data():
    return 1, 2


get_data() | FF(lambda x, y: x + y) == 3

Use alias like follow code, you can use map/filter/reduce more conveniently:

from functools import reduce
from pipe import F

Filter = F(F, filter)
Map = F(F, map)
Reduce = F(F, reduce)

range(100) | Filter(lambda x: x % 2) | Map(lambda x: x * x) | Reduce(lambda x, y: x + y)

Set Global

Maybe you don't want to use from pipe import F in every file of the entire project, you can use the following code to set it as a global function, just like min/max/sum.

import pipe

pipe.set_global(pipe.F, pipe.FF)

Maybe you also want to expose functools.reduce to the world, just like map/filter.

import pipe
import functools

pipe.set_global(pipe.F, pipe.FF, functools.reduce)

More

No more ~ This library has less than ten lines of valid code, but it is very effective.
