| Python toolchains can be utilized in other bazel rules, such as `genrule()`, by adding the `toolchains=["@rules_python//python:current_py_toolchain"]` attribute. You can obtain the path to the Python interpreter using the `$(PYTHON2)` and `$(PYTHON3)` ["Make" Variables](https://bazel.build/reference/be/make-variables). See the | ||
| {gh-path}`test_current_py_toolchain <tests/load_from_macro/BUILD.bazel>` target for an example. | ||

figure out how to define a toolchain and what the different pieces me.
This gives some more explanation of the toolchain types, what they do, and how to
define them.
