| `# gazelle:python_generation_mode_per_file_include_init`| `package` |
| Controls whether `__init__.py` files are included as srcs in each generated target when target generation mode is "file". Can be "true", or "false" | |
| `# gazelle:python_library_naming_convention`| `$package_name$` |
-| Controls the `py_library` naming convention. It interpolates \$package_name\$ with the Bazel package name. E.g. if the Bazel package name is `foo`, setting this to `$package_name$_my_lib` would result in a generated target named `foo_my_lib`. | |
