See all- Online: SD Python Saturday Study GroupLink visible for attendees
San Diego Python Usergroup is continuing their weekend Study group online in their discord server.
The meetup format is voice forward, with screen sharing encouraged. Chat, learn, and hang out.
This study group is for everyone on their Python journey, whether you're just starting out, an experienced pro, or anywhere in between. There's no formal instruction, just a bunch of folks who like to code. Sometimes we talk about a specific subject, sometimes answer questions, whatever!

Attendees hail from a variety of sources including, but not limited to: we San Diego PyLadies (https://www.meetup.com/sd-pyladies)
Open BioInformatics San Diego (https://www.meetup.com/Open-Bioinformatics-SanDiego/)
San Diego Artificial Intelligence (https://www.meetup.com/SanDiegoAI/))Python Community Code of Conduct (http://www.pythonsd.org/coc): Python is much more than a software language. Python is a vibrant community made up of members from around the globe with a diverse set of skills, personalities, and experiences. It is through these differences that our community experiences great successes and continued growth. Overall, we're good to each other. We contribute to this community not because we have to, but because we want to.
- CalPy @ Prompt Driven Launch Party presented by Toolhouse500 Global HQ, Palo Alto, CA
RSVP here:
https://lu.ma/arq0umjrThis month's meeting will be in person at the launch party for last month's presentation on "Prompt Driven Development". We'll stream to Zoom as best we can.
PDD Launch event:
Ever feel like using Claude Code or Cursor is similar to throwing a grenade in the codebase? You are never sure what will be added, deleted or duplicated. As the codebase grows, the agentic coder starts adding more bugs than it fixes?Prompt-Driven Development (PDD) replaces the traditional patch-and-maintain model with a regenerative approach that keeps software clean, consistent, and easy to evolve. Instead of repeatedly editing tangled code, PDD treats the natural-language prompt as the single source of truth.
The PDD CLI sync loop injects dependencies, generates multi-language code, writes unit tests, fixes crashes, and updates the prompt in one run. Changes are made at the high-level prompt, and the system regenerates fresh code, avoiding the accumulation of technical debt and reducing long-term maintenance effort.
PDD delivers higher reliability, lower costs, and less active developer time by freeing engineers from constant AI supervision. Developers can work in cloud mode with GitHub SSO and high-end models or locally with their own keys, making it suitable for everything from rapid prototypes to enterprise-grade systems with predictable speed, quality, and scalability.

Groq will be giving every attendee $20 Groq credit on Prompt Driven.
Toolhouse.ai - Toolhouse allows everyone to vibe code agents with superpowers. Type what your agent should do in your own words: Toolhouse creates a bulletproof agent pre-loaded with scrapers, web search, MCP servers, RAG, and more. Toolhouse publishes and hosts agents for you, so they will work when you close your laptop. Toolhouse is trusted by over 5,000 users, including vibe coders and engineers from large companies like Cloudflare, Snowflake, Qualcomm, and NVIDIA.Agenda
