… and now we have also moved the pytest configuration to the pyproject.toml file: https://python-basics-tutorial.readthedocs.io/en/latest/test/pytest/config.html

Since tox 4.44.0, tox.ini has been frozen. Only the toml configuration is supported for further development. We have therefore updated our tutorial accordingly: https://python-basics-tutorial.readthedocs.io/en/latest/test/tox.html #Python #testing #tox

We are pleased that we were able to develop an idea on how to better deal with LLM agents in the future.

Git 2.53 provides faster insights into the repository structure with 'git repo structure'. However, to better understand this, it is helpful to be more familiar with the inner workings of Git. That is why we have expanded our tutorial to include Git data and storage models: https://www.python4data.science/en/latest/productive/git/advanced/internals.html

We have updated the FastAPI extensions. It is very surprising to us that millions of extensions are being downloaded that have not been updated for over a year.

We have updated the section on pytest with many exciting use cases
* on command line options
* on generating markers
* and on parameterising exceptions

@webology Step by step, we will document our experiences with programming support from LLM agents in the tutorial. Our blog posts are somewhat more abstract, such as the one about how we use LLMs: https://cusy.io/en/blog/how-llms-help-us-with-programming.html

We have now described how to create a configuration for Claude Code so that it uses uv reliably: https://python4data.science/en/latest/productive/envs/uv/claude.html

Since we have recently been asked frequently whether pandas is slow and whether we should use Polars, Dask or DuckDB instead, we have now provided an initial overview of the various technologies: https://www.python4data.science/en/latest/workspace/pandas/index.html#pandas-vs-polars-vs-dask-and-duckdb
