I’m looking to test against multiple versions of Python using parameterize and

__defaults__

using something similar to the example:

# BUILD
__defaults__({
    python_tests: dict(
        interpreter_constraints=parametrize(py2=["==2.7.*"], py3=["==3.6.*"]),
    )
})

Which means that my python_tests targets now have multiple owners:

➜ pants list file.py                
file.py:../file_tests@interpreter_constraints=py2
file.py:../file_tests@interpreter_constraints=py3

I perform a check for multiple owners using a script in CI, but would like to exclude owners that are a result of this parameterize, is there a way I can filter these out from

pants list

?
