What's in the pack

Installing this pack installs these 7 extensions. Each one works on its own, so you can disable or uninstall any you don't need.

Nifty Python Envs: See and manage every Python environment: project venvs (uv or venv), uv-managed Pythons, conda and pyenv. Create, activate in terminals, pick for the workspace, and manage packages.
Nifty pytest: A pytest test explorer with saved run configurations, marker filters, real assertion diffs, rerun-failed and slowest-test reports.
Nifty Python Profiler: Profile Python scripts and pytest runs with cProfile: hotspot table, call counts and timings inline next to each function.
Nifty Python REPL: Send lines, blocks and # %% cells to a Python or IPython REPL that stays open, with multi-line code that just works, run-and-advance and cell lenses.
Nifty Docstrings: Type three quotes under a Python function and get a Google, NumPy or Sphinx docstring with its arguments, types, returns and raises. PHPDoc, Rust and Go doc comments too.
Nifty Paired Notebooks: Keep Jupyter notebooks paired with plain Python (percent format) or Markdown files: readable git diffs, edit either side, outputs kept, and open any .py script as a notebook.
Nifty Notebook Servers: Manage Jupyter servers from the side bar: see kernels and sessions, shut down, restart or interrupt kernels, and browse, open and edit the server's files directly.

VS Code: search for "Nifty Python Pack" in the Extensions view, or install from the Visual Studio Marketplace.
Cursor, Windsurf, VSCodium, Kiro, Antigravity: install from Open VSX.

This extension collects no telemetry and needs no account.
