Streamlined Python Scripting with uv and PEP 723

uv is a fast Python package and project manager written in Rust that provides uvx for one-off script execution by auto-creating disposable virtual environments and installing dependencies.

PEP 723 specifies inline metadata for single-file Python scripts, allowing scripts to declare Python version requirements and dependencies.

Combining uv with PEP 723 metadata and a shebang line enables seamless executable Python scripts without manual environment setup.

Examples include using uvx to run tools like ruff, a PEP 723 script to fetch PEP titles, and an executable YouTube transcript downloader script with uv run --script shebang.
