Hot function generators
Project description
library with some helper functions that make more functions for you.
check it out
make a plucker with pluck:
from fnny import pluck as p from collections import namedtuple G = namedtuple("G", ["a"]) guys = [G(i) for i in range(10)] expected = sum(map(lambda x: x.a, guys)) actual = sum(map(p.a, guys)) assert expected == actual
call a method with method:
from fnny import method as m from test.test_it import _Argless() no_args = [_Argless() for a in range(10)] expected = list(map(lambda x: x.wow(), no_args)) actual = list(map(m.wow, no_args)) assert expected == actual
use a partially applied method with partial:
from fnny import partial as pa from test.test_it import _OneArg() has_args = [_OneArg() for a in range(10)] expected = list(map(lambda x: x.add(1), has_args)) actual = list(map(pa.add(1), has_args)) assert expected == actual
partial even supports kwargs:
from test.test_it import _OneKwarg() has_args = [_OneKwarg() for a in range(10)] expected = list(map(lambda x: x.derp(something="heyy"), has_args)) actual = list(map(pa.derp(something="heyy"), has_args)) assert expected == actual
but actually, python already has a way more idiomatic way to do all of the above:
guys = [G(i) for i in range(10)] assert sum(map(lambda x: x.a, guys)) == sum(g.a for g in guys) no_args = [_Argless() for a in range(10)] expected = list(map(lambda x: x.wow(), no_args)) actual = [argless.wow() for argless in no_args] assert expected == actual has_args = [_OneArg() for a in range(10)] expected = list(map(lambda x: x.add(1), has_args)) actual = [one.add(1) for one in has_args] assert expected == actual has_kwargs = [_OneKwarg() for a in range(10)] expected = list(map(lambda x: x.derp(something="heyy"), has_kwargs)) actual = [kw.derp(something="heyy") for kw in has_kwargs] assert expected == actual
But maybe there’s still a place for a discriptor-based lib for function generation.
I’ll add examples as soon as I think of them, I guess.
