PEX Packaging Toolchain

PEX (Python EXecutable) is a powerful Python packaging tool that creates self-contained Python environments, known as PEX files. These files bundle Python code, dependencies, and optionally a Python interpreter into a single executable, making applications portable and ensuring reproducible builds without needing `pip` or virtual environments on the target system. It simplifies deployment by providing a single artifact. The current version is 2.92.1, and it maintains a rapid release cadence with frequent bug fixes and feature enhancements.
