Use partial function application in Python

Pypartial is a simple Python library that allows the use of partial function application notation in native Python. It is extremely useful when trying to write concise and clear code, and extends the ease offered by Python’s functional programming features.

Example:

import pypartial #use <_ notation to partial apply functions

binary = int<_(base=2) #you can pass keyword arguemnts print(binary(‘101010100101’))

import random dice=random.randint<_(1, 6) #you can also pass non-keywords print(dice()) print(dice())

up_to_ten = range<_(_, 11) #you can leave args blank with ‘_’ print(list(up_to_ten(5)))

import operator double = operator.mul<_(2) print(double(7))

class Foo(object):

def bar(self, a, b):

print([a,b])

def egg(self, a, b, c=9):

print([a,b,c])

foo=Foo() bar7 = foo.bar<_(_, b=7) #works with methods too bar7(2)

egg1 = foo.egg<_(_, 5) egg2 = egg1<_(c=9) #you can partially apply multiple times egg2(6)

print(egg2) #nice string representation
