Accelerate Python Project Management with UV

Introduces uv as a Rust-built, drop-in pip-compatible package installer claiming 10-100x faster installs than pip, plus an integrated virtual environment manager, Python version installer, advanced dependency resolver, and lockfile support, and contrasts it against pip (10-100x faster, better resolver), pip-tools (faster, simpler), poetry (faster, less opinionated), and conda (faster, Python-focused) - with measured benchmarks in the source showing pip at roughly 30 seconds versus uv at roughly 2 seconds, poetry at roughly 20 seconds versus uv at roughly 3 seconds, and pip-tools at roughly 15 seconds versus uv at roughly 2 seconds. Covers installation across platforms (a shell installer for macOS and Linux, a PowerShell installer for Windows, plus pip, Homebrew, and cargo alternatives) and 22 patterns: project creation and dependency install, virtual environment creation and activation or skipping activation via uv run, adding, removing, and upgrading dependencies including from git or a local path, locking dependencies to uv.lock, installing and pinning Python versions via .python-version, pyproject.toml configuration, migrating from requirements.txt or Poetry, monorepo workspace support, CI/CD integration, single- and multi-stage Docker integration, lockfile workflows including exporting to requirements.txt with hashes, the global cache and its per-OS location, parallel installation control, and offline mode. Closes with common new-project and existing-project workflows, pre-commit hook and VS Code integration, a troubleshooting section covering uv not found, wrong Python version, dependency conflicts, cache issues, and an out-of-sync lockfile with each issue's fix, performance tips, migration guides from pip plus requirements.txt, Poetry, and pip-tools with before and after commands, and an essential command reference.

Use it when installing or managing Python dependencies with uv, creating or managing virtual environments, managing Python versions, migrating from pip, Poetry, or pip-tools, or setting up uv in CI/CD or Docker. Skip it for anything unrelated to the uv package manager or outside this scope.

Input is a Python dependency or environment management task - installing a package, creating a venv, pinning a Python version, or migrating an existing project; output is the matching uv command or configuration: pyproject.toml entries, a .python-version file, a uv.lock, a Dockerfile stage, or a CI workflow step.

Compatible with pip, pip-tools, and Poetry workflows for migration; integrates with git and local paths for dependency sources, GitHub Actions for CI/CD, Docker for containerized builds, pre-commit for hooks, and VS Code for editor integration.

Python developers and teams adopting uv for faster dependency management who need concrete commands across installation, environments, locking, CI/CD, and migration from pip, Poetry, or pip-tools rather than piecing together uv's CLI from scattered documentation.
