But another question. Custom pants targets have to be written in python 2.7, right? I’m trying to find a way to have both 2.7 and 3 code coexist within my monorepo. In our CI script we just run

./pants --changed-parent="${COMMIT_ID}" --changed-include-dependees=transitive test

when running tests but that fails if you have targets that are using python 3 and others using 2.7. Is there any recommended way to work around this?
