| :::{bzl:target} toolchain_type |
| |
| Identifier for the toolchain type for the target platform. |
| |
| This toolchain type gives information about the runtime for the target platform. |
| It is typically implemented by the {obj}`py_runtime` rule. |

| :::{bzl:target} exec_tools_toolchain_type |
| |
| Identifier for the toolchain type for exec tools used to build Python targets. |
| |
| This toolchain type gives information about tools needed to build Python targets |
| at build time. It is typically implemented by the {obj}`py_exec_tools_toolchain` |
| rule. |

| :::{bzl:target} current_py_toolchain |
| |
| Helper target to resolve to the consumer's current Python toolchain. This target |
| provides: |

| ::::{target} autodetecting_toolchain |
| |
| Legacy toolchain; despite its name, it doesn't autodetect anything. |

| :::{deprecated} 0.34.0 |

| Use {obj}`@rules_python//python/runtime_env_toolchains:all` instead. |

| :::{target} none |
| A special target so that label attributes with default values can be set to |
| `None`. |
| |
| Bazel interprets `None` to mean "use the default value", which |
| makes it impossible to have a label attribute with a default value that is |
| optional. To work around this, a target with a special provider is used; |
| internally rules check for this, then treat the value as `None`. |
