Autopartial

This is a simple library that provides a decorator that allows your to apply a function partially. In other words, it allows you to curry a function with some of its arguments, from left to right.

Installation

After cloning this repository, you can install the package by running the following command in the root directory of the repository:

pip install autopartial

Usage and example

The main use case is to decorate a function definition with @autopartial.

An example can is in main.py. It contains the following code:

from autopartial import autopartial

@autopartial
def add(x, y):
	return x + y

if __name__ == '__main__':
	x = 10
	y = 20

	add_10 = add(x)	 # add(x): y -> x + y
	print(add_10(y)) # 30

Here, the add function takes 2 arguments and returns its sum. You can now partially apply the argument x to add by calling add(x). This returns a new function that takes only one argument y and returns x + y.

In the example above, add(10) returns a function add_10 that always adds 10 to its input.

You can run this example, after installing this package, by running the following command from the root of the repository:

python main.py
