Using uv and PEP 723 for Self-Contained Python Scripts

Sharing single-file Python scripts with external dependencies is now easy thanks to uv and PEP 723, which enable embedding dependency metadata directly within scripts. This approach eliminates the need for complex setup tools like requirements.txt or package managers, making script distribution and execution seamless and simplifying deployment while maintaining flexibility and efficiency. We all love Python’s comprehensive standard library, but let’s face it – PyPI’s wealth of packages often becomes essential. Sharing single-file, self-contained Python scripts that rely on these external tools can be a headache. Historically, we’ve relied on requirements.txt or full-fledged package managers such as Poetry or pipenv, which can be overkill for simple scripts and intimidating for newcomers. But what if there was a simpler way? That’s where uv and PEP 723 come in. This article delves into how uv harnesses PEP 723 to embed dependencies directly within scripts, making distribution and execu ... Read full article.
