./pants py-constraints [args]
Determine what Python interpreter constraints are used by files/targets.
Backend: pants.backend.python.mixed_interpreter_constraints
Config section: [py-constraints]
Basic options
None
Output the goal's stdout to this file. If unspecified, outputs to stdout.
False
Output a CSV summary of interpreter constraints for your whole repository. The headers are Target
, Constraints
, Transitive Constraints
, # Dependencies
, and # Dependees
.
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.
