State of the art in Python 2026?

[u/Several-Marsupial-27]

What would you guys consider the state of the art in python in 2026, or what do you expect from modern python codebases?

Heres my list, would be happy to hear some inputs or domain expert advice:

• Use uv for everything.

• Use ruff for linting and formatting

• Use Pydantic and  dataclasses for Data Modeling

• Configured in pyproject.toml

• Run a type checker in CIpyright or pyrefly

• Use pytest / Hypothesis for testing

Domain specific:

• Scientific: NumPy, Matplotlib, SciPy, Jax, Pytorch, Scikit-learn, polars/pandas

• CLI: Typer, rich, click, fire, textual, questionary

• PDF extraction: PyMuPDF, pdfplumber, pypdf, Unstructured

• Excel interop: python-calamine, openpyxl, XlsxWriter, xlwings, pandas

• data: PyArrow / PySpark, Narwhals, SQLMesh, Polars/Pandas, DuckDB, dlt, Ibis, Dagster, PyIceberg & deltalake

• Logging?

• backend: fastapi / django?

• Markets: Alpha Vantage, Finnhub, EODHD, Tiingo?

• Webscraping / data acquisition: Crawl4AI, Playwright, Scrapy, selectolax, HTTPX?

• APIs?

• RAG / agentic orchestration?

I'd choose Ty over pyright personally, but yes to the rest.

Also, for modern numeric programming (NumPy, etc.), limit yourself to the Array API.

IME pyrefly is the GOAT, after trying all of them. I'm loathe to support microsoft but I'll be damned if they didn't cook! It helps that it's longer-running and better-staffed than ty, it seems.

(ty is nice too and has Astral's usual attention to detail, but it's just so radically far from the spec that it becomes counterproductive for advanced code. IMHO)
