Project description

# Building Python Extension Modules in Assembly

![GitHub Actions](

This repository is a proof-of-concept to demonstrate how you can create a Python Extension in 100% assembly.


  • How to write a Python module in pure assembly

  • How to write a function in pure assembly and call it from Python with Python objects

  • How to call the C API to create a PyObject and parse PyTuple (arguments) into raw pointers

  • How to pass data back into Python

  • How to register a module from assembly

  • How to create a method definition in assembly

  • How to write back to the Python stack using the dynamic module loader

  • How to package a NASM/Assembly Python extension with distutils

The simple proof-of-concept function takes 2 parameters,

`default >>> import pymult >>> pymult.multiply(2, 4) 8 `

## But, Why?

Just because it can be done.

Also, I want to see if some AVX/AVX2 instructions (high-performance matrix multiplication especially) can be used directly from Python.
