fix: replace eval with ast.literal_eval; ruff linting strings.py: When reading csv export files, use the safer literal_eval to evaluate the fields. Issue pointed out by ruff linter. Other Cleanup: sort imports replace if, else, if, else with if, elif, else use isinstance with tuples rather than 'isinstance() or isinstance()' test_anypy.py: Added tests for tuples, and booleans. Also added exception handling for malformed strings, booleans, tuples.
