A practical, step-by-step roadmap to learn how to:
- Build reusable Python SDKs
- Package and publish them
- Use them in Jenkins pipelines
- Automate real-world SRE workflows (alerts, infra, APIs)
🧠 Big Picture Architecture
Python Script → Internal SDK → HTTP API → External System → Jenkins (cron/scheduled execution)
You are learning how to build internal automation platforms, not just scripts.
📚 Phase 1: Python Foundations (Automation-Focused)
What to Learn
- Functions, modules, imports
- Virtual environments (venv)
- JSON & YAML handling
- Exception handling
- Basic classes & objects

🌐 Phase 2: APIs First (Before SDKs)
What to Learn
- HTTP methods: GET, POST, DELETE
- Headers & authentication
- JSON request/response
- Status codes
- Timeouts & Retries
Resources

👉 https://developer.mozilla.org/en-US/docs/Web/HTTP📦 Python requests Library
👉 https://docs.python-requests.org/⚡ FastAPI Tutorial (API understanding)
👉 https://fastapi.tiangolo.com/
🧪 Practice
Write a script that:
- Calls an API
- Fetches data
- Sends POST request
- Deletes a resource
📦 Phase 3: Python Packaging (VERY IMPORTANT)
What to Learn
- setup.py vs pyproject.toml
- pip install mechanics
- wheel format
- package versioning
- private package repositories
Resources
📘 Python Packaging User Guide

👉 https://python-poetry.org/docs/📦 Twine (Publishing Packages)
👉 https://twine.readthedocs.io/🌐 Real Python Packaging Guide
👉 https://realpython.com/pypi-publish-python-package/
🧪 Practice
- Create a Python package
- Build it (
python -m build) - Install locally using
pip - Import it in another project
🏗️ Phase 4: Building SDK-Style Code
What to Learn
- Class-based design
- Client abstraction
- BaseClient pattern
- Error handling
- Code structure
Typical SDK Structure
my_sdk/
├── client.py
├── base_client.py
├── models.py
├── exceptions.py
├── utils.py
└── init.py

👉 https://www.cosmicpython.com/📘 Fluent Python (Advanced)
👉 https://www.oreilly.com/library/view/fluent-python/9781492056348/
🧪 Practice
Build a client like:
client = MonitoringClient()
client.create_event()
client.get_events()
client.delete_event()
⚙️ Phase 5: Jenkins + Python Integration
What to Learn
- Jenkins pipelines (Jenkinsfile)
- Running Python scripts
- Environment variables
- Cron scheduling
- Dependency installation (pip in pipeline)
Resources
📘 Jenkins Pipeline Docs

🧪 Practice
Create pipeline:
- Install package via pip
- Run Python script
- Capture output
- Trigger via cron
🧪 Phase 6: Testing (CRITICAL for SRE)
What to Learn
- pytest basics
- mocking APIs
- testing client methods
- safe execution patterns
Resources
📦 pytest Documentation
👉 https://docs.pytest.org/📘 Python Testing with pytest
👉 https://pragprog.com/titles/bopytest/python-testing-with-pytest/🌐 Real Python Testing Guide
👉 https://realpython.com/pytest-python-testing/
⚡ Phase 7: Async Python (Advanced)
What to Learn
- async / await
- event loop
- concurrent API calls
- async HTTP clients
Resources

👉 https://docs.python.org/3/library/asyncio.html📦 HTTPX (async HTTP client)
👉 https://www.python-httpx.org/
🧱 Real-World Pattern You Are Learning
This pattern is used everywhere in platform engineering:
- Internal Python SDK
- Published as package
- Stored in private repo
- Installed in pipelines
- Used for automation tasks
- Triggered via cron
🔥 Mini Project (Must Do)
Project: Monitoring Automation SDK
Structure

- Run Python scripts
Day 2
- Learn requests
- Call an API
Day 3
- Write API client class
Day 4

🧠 Final Insight
You are not learning Python.
You are learning to build:
👉 Internal Developer Platforms
👉 Automation of Toolings,API and Systems
👉 Reusable Engineering Tools used internally and are created using Python
This is exactly what strong SREs/DevOps and Platform Engineers do.
This is how in future you can even contribute to Open Source Software
🚀 Next Step : Coming Soon (WIP)
👉 A complete working project template (SDK + Jenkins + API mock).
👉 Tailored to this above workflow.
Just share it further on LinkedIn, Substack 👍
