# This target can be used to inspect the current Python major version. To use,
# put it in the `flag_values` attribute of a `config_setting` and test it
# against the values "PY2" or "PY3". It will always match one or the other.
#
# If you do not need to test any other flags in combination with the Python
# version, then as a convenience you may use the predefined `config_setting`s
# `@bazel_tools//tools/python:PY2` and `@bazel_tools//tools/python:PY3`.
#
# Example usage:
#
#     config_setting(
#         name = "py3_on_arm",
#         values = {"cpu": "arm"},
#         flag_values = {"@bazel_tools//tools/python:python_version": "PY3"},
#     )
#
#     my_target(
#         ...
#         some_attr = select({
#             ":py3_on_arm": ...,
#             ...
#         }),
#         ...
#     )
#
# Caution: Do not `select()` on the built-in command-line flags `--force_python`
# or `--python_version`, as they do not always reflect the true Python version
# of the current target. `select()`-ing on them can lead to action conflicts and
# will be disallowed.
