This example shows a project that has Gazelle setup with the rules_python extension, so that targets like py_library and py_binary can be automatically created just by running
$ bazel run //:gazelle
As a demo, try creating a __main__.py file in this directory, then re-run that gazelle command. You'll see that a py_binary target is created in the BUILD file.
Or, try importing the requests library in __init__.py. You'll see that deps = ["@pip//pypi__requests"] is automatically added to the py_library target in the BUILD file.
For more information on the behavior of the rules_python gazelle extension, see the README.md file in the /gazelle folder.
