A new project, written in Rust, aims to make it easier to package and distribute a Python application as a standalone binary executable—something that has long been a pain point for Python developers.
PyOxidizer, according to its GitHub README, is “a collection of Rust crates that facilitate building libraries and binaries containing Python interpreters.” With PyOxidizer, its developers claim, it’s possible to build an executable for a Python app that embeds a Python interpreter, with no other runtime dependencies.
PyOxidizer requires an installation of Rust 1.31 or better, and packages only apps written with Python 3.7. To use PyOxidizer, the developer creates a TOML file that describes how to embed a given Python app, then builds and runs PyOxidizer with an environment variable pointing to that TOML file.
