Real Python’s Post

Claude code source leak -> rewrite it in python with codex -> 50k+ github stars That’s why we need experts in the loop. Agree?

Built a Django performance layer using PyO3 + Rayon. I tried to replace DRF's serialization loop with Rust. Big wins, but the Python↔Rust bridge is still the main cost. Would love feedback from people who built similar bridges. https://lnkd.in/dS_k8UGi

How much Claude Opus 4.6 (1M) costs: After hitting the Max limit, it wrote 5,000 lines of Python code (data extraction pipeline), ran the code, tested it (text-only output as JSON), and fixed errors. It costs about $20. 😁 ($0.004 per line of Python code.)

I kept seeing coding agents drift into pip install, raw python, and manual dependency edits in Python projects. It works until it doesn’t, and the inconsistency becomes annoying fast, especially when the agent also uses small background Python scripts you did not explicitly ask for. This post is a short reflection on that pattern and the small uv-first setup I now use to keep Claude Code and Codex more consistent across runs. I wrote up the reasoning, the repo-level instruction approach, and the example setup here: https://lnkd.in/dAvyjEwr

Need to investigate a spike in revenue? Plan your revenue and inventory data so you can compare them side by side. This article covers how to do it with R (and you can plan a similar technique with Python, too!). https://lnkd.in/gZjCqxC9

Uploaded a small Python To-Do CLI project to GitHub today. A simple practice build to get better with Python basics, loops, conditions, lists, and logic building. Trying to stay consistent with small daily projects and learn by actually building. GitHub: [https://lnkd.in/gGscJtCP] #Python #GitHub #CodingJourney #PythonProjects #LearningInPublic

‎I’m excited to share that I’ve uploaded a new video on my YouTube channel! 🎥 ‎In this video, I explain the fundamentals of Python Variables and Naming Conventions in a simple and beginner-friendly way. ‎Understanding variables is one of the first and most important steps in programming. I’ve also covered best practices for naming variables, which helps in writing clean and readable code. ‎📌 What you will learn: ‎What are variables in Python ‎How to create and use variables ‎Best naming conventions (camelCase, snake_case) ‎Common mistakes to avoid ‎If you are starting your journey in Python, this video will be very helpful. ‎🔗 https://lnkd.in/drrMXj3F ‎I would really appreciate your support and feedback!
