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. We’ll be using a pre-release of Bazel 9. This course uses these Bazel modules:Documentation Index

- 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. It also manages Python package dependencies.
- 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 wires up the
uvpackage manager, written in Rust, which we’ll use as a fast constraint-solver to resolve requirements.
