pipeit 0.1.4

Syntax suger for python's functional programming as Unix pipes. - GoodManWEN/pipeit

pipeit

This is a super simple wrapper , let's use python functional programming like Unix pipe!

Inspired by abersheeran/only-pipe , czheo/syntax_sugar_python , pipetools

Install

pip install pipeit

Usage

• Statements start with PIPE and end with END.
• There're only two objects(PIPE & END) and three types(Filter ,Map & Reduce) in namespace, so feel free to use from pipeit import *.
• Convert filter into tuple , e.g. map(lambda x:x + 1) => (map , lambda x:x + 1)

Example

Some description.

>>> from pipit import PIPE , END , Map , Filter , Reduce

>>> data = PIPE | range(10) | (map , lambda x:x + 1) | (map , str) | list | END
>>> data
['1', '2', '3', '4', '5', '6', '7', '8', '9', '10']

# (map , lambda x:x + 1) equals to Map(lambda x:x + 1)
>>> func = lambda x: PIPE | range(x) | Map(lambda x:x + 1) | Map(str) | list | END
>>> func(10)
['1', '2', '3', '4', '5', '6', '7', '8', '9', '10']

# Or you may want more easy use.
>>> range(10) | Filter(lambda x:x<5) | list
[0, 1, 2, 3, 4]

>>> for _ in range(3) | Map(str):
        print(repr(_))
