Python is one of the most popular languages at Google. Add Python to your Bazel setup, with all the common developer workflows. This course assumes students have completed [Bazel 101](/learning/bazel-101/).

We'll be using a pre-release of Bazel 9.

This course uses these Bazel modules:

* [https://registry.bazel.build/modules/rules\_python](https://registry.bazel.build/modules/rules_python) is the “standard” ruleset for Python. It provides a pre-built, “mostly statically-linked” interpreter from [https://github.com/astral-sh/python-build-standalone](https://github.com/astral-sh/python-build-standalone). It also manages Python package dependencies.
* [https://registry.bazel.build/modules/aspect\_rules\_py](https://registry.bazel.build/modules/aspect_rules_py) adds an understanding of Virtual Environments (”virtualenv”) which makes tools like Editors and Debuggers work the way you expect.
* [https://registry.bazel.build/modules/rules\_uv](https://registry.bazel.build/modules/rules_uv) wires up the `uv` package manager, written in Rust, which we’ll use as a fast constraint-solver to resolve requirements.
