Add tests/lint/repository/test_task_file_numbering.py: numbered task files use exactly two leading digits, a numbered *_core.yml must be 00_core.yml, per directory the numbers are unique/consecutive and start at 01 (00 with a core file), numbered includes appear in ascending order, and shared helpers live in tasks/utils/ instead of the numbered chain. Apply it across every role: rename NN_core.yml to 00_core.yml with a consecutive down-shift of the siblings, move letter-suffix children into a subdirectory named after their parent task, relocate helpers included from more than one place into tasks/utils/, and update every reference (include_tasks, path_absolute, .ansible-lint-ignore, requirement docs). Legacy narration comments in the touched files are deleted; the upstream xwiki.properties reference block opts out via nocheck. The unused MAILU_IP6_PUBLIC var (only ever named in now-removed comments) is dropped. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Python Development Utilities
Description
This Ansible role sets up a Python development environment on Arch Linux. It includes Python itself, the pip package manager, and builds on the general developer persona to support scripting, application development, data science, and more.
Learn more at the Python Official Site, the Arch Wiki - Python, and Wikipedia – Python.
Overview
This role provides the essential tooling for Python developers, enabling immediate use of python and pip from the command line. It supports both general-purpose scripting and advanced software engineering workflows.
Cosmos
The diagram places Python Development Utilities in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid 1:1 edges are fixed relationships; dashed 0..1 edges are conditional (enabled only in matching deployments). Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in meta/main.yml.
Purpose
To simplify and standardize the provisioning of Python-ready environments for developers, students, data scientists, and automation engineers.
Features
- Installs Python and Pip: Ensures the interpreter and package manager are available.
- Prefers Python 3.11+: Installs Python 3.11+ where available and makes it the default via
/usr/local/bin/python3and/usr/local/bin/pip3. - Persona Integration: Extends
dev-corewith Python-specific tools. - Foundation for Further Stacks: Ideal starting point for Flask, Django, scientific computing, and automation.
Supported distro families in the installer script:
- Arch Linux
- Debian
- Ubuntu
- Fedora
- CentOS / RHEL
Customization
Easily extend this role with:
- Python virtualenv tools (
python-virtualenv,pyenv) - Popular libraries (
numpy,requests,flask) - Framework-specific roles (e.g.,
dev-python-django)
