./pants py-constraints [args]
Determine what Python interpreter constraints are used by files/targets.
Output the goal's stdout to this file. If unspecified, outputs to stdout.
Output a CSV summary of interpreter constraints for your whole repository. The headers are
# Dependencies, and
This information can be useful when prioritizing a migration from one Python version to another (e.g. to Python 3). Use
# Dependencies and
# Dependees to help prioritize which targets are easiest to port (low # dependencies) and highest impact to port (high # dependees).
Use a tool like Pandas or Excel to process the CSV. Use the option
--py-constraints-output-file=summary.csv to write directly to a file.
