python-uv

You can run a Python script with automatic dependency management using uv. By embedding dependencies inline via PEP 723 or executing with uv run --with, the script runs in an isolated environment, preventing system Python pollution without requiring manual package installation.

PEP 723 inline metadata is a standard for embedding dependency declarations directly within Python scripts. It enables self-contained scripts and templates for CLI tools, data processing, and API clients by declaring required packages in a metadata block, allowing the script to be easily distributed and run portably.

Yes, you can execute an existing Python script without modification by using the uv run --with command. This workflow automatically resolves and injects the missing dependencies at runtime, allowing you to quickly test or execute scripts without altering their original source code.

Yes, uv run supports creating portable CLI tools and data processing scripts. It provides templates for common script types and uses inline dependency management to ensure your scripts are self-contained, enabling rapid distribution and execution across different environments without conflicts.

You should use uv run for quick Python scripting to bypass the overhead of creating and activating virtual environments. It automatically handles dependency resolution and isolation on the fly, preventing system Python contamination while accelerating the testing and execution of self-contained scripts.
