Python

Preferred language for AI & data science because it is world-wide the leading programming language for AI & data science by far.

We also prefer Python for scripting tasks over Shell Scripts (or other scripting languages) when the following conditions apply:

• There is no obvious candidate for a scripting language for the task at hand in the context of the current tech stack. E.g. a certain product may include a default scripting language within its tech stack. This may then be a more logical candidate.
• The logic to be implemented is non-trivial, but also not overly complex. If the logic is very simple a Shell Script is often a better choice because it is a very standard solution and Python will quickly be overkill. If the logic is too complex then a script may not be the best solution in any case and it will make sense to look into a proper (backend) software solution to implement the logic.

Tooling

• uv manages Python versions, virtual environments and dependencies with a lockfile, replacing pip, pyenv and Poetry with one fast tool.
• Ruff for linting and formatting.
• ty for type checking. It is still in beta, so use mypy or Pyright where it does not cover your needs yet.
