"I know some Python basics. Where do I start with data?"

Start with this path. Set up a notebook → load and clean real data → make charts → finish with statistics.

Turn a folder of PDFs, Excel files and images into clean Markdown your LLM can actually read.

The MarkItDown course shows the Python code, the batch run and the MCP server. Plus where it falls short next to Pandoc.

The GIL doesn't make threaded Python code safe. It can just make thread bugs very rare.

Nathan Goldbaum can't confirm it, but suspects that's behind some hard-to-debug flaky crashes. On the free-threaded build, he says, they usually show up right away.

Pick a year and a round, and this Python app replays the F1 race on a drawn track, with live positions, tyres and the Safety Car.

The F1 data has no GPS for the Safety Car, so the app has to fake its position.

Using a list as a queue works fine. Until the queue gets big.

A deque gives you fast appends and pops at both ends. This course shows when to reach for it over a list.

Learn Codex this Saturday and Sunday with @philippacsany: https://t.co/u6ky0faNNU

[Real Python @realpython]

What line do you add to your prompts?

[Philipp Acsany @philippacsany]

5 lines I add to almost every prompt for Codex, or any coding agent 🧵

1. Ask me questions
2. Official docs only
3. Another developer
4. Only if confident
5. Report back

Claude Code, Cursor and GitHub Copilot each run in your editor, your terminal, your pull requests and the cloud.

Let the task pick:

1. Editor: edits you approve
2. Terminal: multi-file changes
3. PRs: work you don't watch
4. Cloud: scoped jobs
5. Where cloud agents run

🧵

[Real Python @realpython]

5. Where cloud agents run depends on the vendor.

Claude Code on the web: Anthropic's servers.

GitHub Copilot cloud agent: a short-lived GitHub Actions environment.

Cursor Cloud Agents: optionally your own machines.

Check your company's policy for private code.

Your dataset is bigger than your machine's memory.

A generator hands you one item at a time instead of loading it all. Chain a few and you've got a data pipeline.
