Is CodeMentor AI free?

The first 15 Python lessons are free with no signup and no credit card. After that, the 7-day Pro trial unlocks every track; cancel anytime. Pro is $12/month or $89/year.

Can I learn Python without installing anything?

Yes. Every lesson runs Python in your browser — Skulpt for lightweight lessons and Pyodide (full CPython) on the playground. No Anaconda, no pyenv, no terminal commands. Open the page and hit Run.

Is CodeMentor AI good for complete beginners?

Yes — the Foundations track starts with print('Hello, World!') and assumes zero programming background. The first 15 lessons are free to verify the difficulty curve matches you before any signup.

Does the AI tutor replace a human mentor?

It replaces 80% of "I'm stuck at 21:00 and Stack Overflow scared me" moments. You get hints calibrated to your code + a chat for follow-up questions. For project review and career advice the team also answers support@learnpython.academy directly.

Can I learn Python for an AI engineering job?

Yes. The AI Engineering track covers production patterns the US dev community uses in 2026 — Claude/LLM APIs, tool use, RAG, agent loops, prompt caching, evals, voice agents. Build production AI features end-to-end.

Are the courses available in languages other than English?

Yes — the platform UI and most lessons are translated into 18 languages including Ukrainian, Russian, Polish, German, French, Spanish, Portuguese, and more. Pick yours in the language switcher.

DevOps for Python

L4PRO· 104 lessons

Docker, CI/CD, observability, deploys, incident response

0 / 104 · 0%

104 lessons across 6 modules: Docker + containers, CI/CD + GitHub Actions, Kubernetes + orchestration, observability + logging, cloud + IaC + secrets + cost, plus the modern stack (Helm, ArgoCD GitOps, Vault, Argo Rollouts, chaos engineering, FinOps).

✅ Before you start

·You've shipped at least one Python app (FastAPI, Flask, Django — anything that runs).
·Terminal comfort: cd, ls, grep, ssh. We assume bash basics
·A free-tier account on AWS / GCP / Fly.io / Render — we deploy to one of these in module 5

→ After you finish

ℹ️ Heads-up on the format: These lessons are concept explanations + quizzes + predict-the-output exercises. The code samples don't execute in your browser because Pyodide can't spin up an HTTP server / database / TCP socket. To run them, copy snippets into your own machine — or pair this track with Foundations (which DOES run live in-browser via Skulpt).
