This is an example Python project with modules that uses rules_python.
This example uses the Nix package manager to provide Python packages, and as such only works with Nix installed. Demonstrating other methods of providing Python packages is out of scope of this example.
To run the example with Nix, issue the following command:
nix-shell --command 'bazel run --config=nix :hello'
To specify Python version or modules, change the python3_attribute_path parameter in the nixpkgs_python_configure call in the WORKSPACE file.
