:::{bzl:target} python

A target to directly run a Python interpreter.

By default, it uses the Python version that toolchain resolution matches (typically the one marked is_default=True in MODULE.bazel).

This runs a Python interpreter in a similar manner as when running python3 on the command line. It can be invoked using bazel run. Remember that in order to pass flags onto the program -- must be specified to separate Bazel flags from the program flags.

An example that will run Python 3.12 and have it print the version

bazel run @rules_python//python/bin:python \
  `--@rule_python//python/config_settings:python_verion=3.12 \
  -- \
  --version
