Python

Curated name python. Installs CPython plus a set of common tools (linters, formatters, pytest, virtualenv) via the upstream devcontainers/features/python feature.

Add it

monoceros init acme --with-languages=python
monoceros add-language acme python:3.12

Note

acme is just a sample workbench name - it’s whatever you passed to monoceros init. Substitute your own throughout.

Remove it

monoceros remove-language acme python

Or delete the entry from acme.yml by hand and re-run monoceros apply acme - the yml is the source of truth.

Pinning a version

monoceros add-language acme python:3.12

Supported: 3.12, 3.11, 3.10, 3.9, 3.8 (also latest).

Key options

Set these by adding the feature directly (see Other feature options):

Option	Default	Notes
version	os-provided	Pin via the :version suffix instead.
installTools	true	Installs flake8, black, mypy, pytest, pylint, …
installJupyterlab	false	Set true to add JupyterLab.

Full option list: upstream feature.

Tip

Project dependencies (Django, FastAPI, …) come from your requirements.txt / pyproject.toml, not from Monoceros - the language gives you the interpreter and tooling.
