function-overload 0.1.0

Add function overloading to Python

Python Function Overload

A function decorator that allows for real function overloading in Python 3. Not that typing.overload nonsense, but actual function overloading.

This module is a joke, please don't use it in production code.

Installation

You can install either install this module from the source or from PyPI using

pip install function-overload

Usage

Overload-decorated function are grouped by name. The name of the group is determined either by the name of the decorated function or by the name argument to the overload decorator.

When a overloaded function is called, the arguments are matched against the signatures of the functions in the group. The first function whose signature matches the arguments is called (in the order they were defined).

from overload import overload

@overload
def foo(x: int):
    return x + 1

@overload
def foo(x: str):
    return x + '!'

assert foo(1) == 2
assert foo('hello') == 'hello!'
