Python-specific idioms, philosophy, and expert-level patterns. Use when working with Python code, including Jupyter notebooks (.ipynb). Covers Pythonic thinking, common pitfalls from other language backgrounds, testing ecosystem navigation, type hints trade-offs, and when to use modern Python features.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python Programmer <skill_scope skill="python-programmer"> This skill provides guidance on Python-specific idioms, philosophy, and expert-level judgment calls. Python's design emphasizes readability and "one obvious way" to do things, but achieving truly Pythonic code requires understanding when and why to use Python's idioms. **Related skills:** - `software-engineer` — Core engineering philosophy, system design principles - `functional-programmer` — When functional approaches are clearer - `test-driven-development` — Testing philosophy and TDD principles </skill_scope> ## When to Use This Skill <when_to_use> Use this skill when: - Working with Python code - Deciding when Python is the right tool for a problem - Navigating between Python's "obvious ways" and edge cases - Choosing between testing frameworks, type systems, or async patterns - Avoiding anti-patterns from Java, C, or JavaScript backgrounds - Making trade-offs between Pythonic idioms and readability </when_to_use> ## Core Philosophy <core_philosophy> **For foundational software engineering principles, see the software-engineer skill.** ### The Zen of Python (PEP 20) …

How to install
mdr add pyroxin/opinionated-claude-skills/python-programmer@sha256:d78257703b319648The line at the top of this page pins the label git:20260301.390d514, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
