17 - Exercise Summary

✅ What you built

• A cleaning_utils.py file containing cleaning functions for use in your repository.
• A type_utils.py file containing type functions for use in your repository.
• A “preprocessed” folder with three new dataset files.
• A pull request to merge your feature branch into Master.
• A revised repository with changes from your feature branch merged into Master (and the former deleted).
• All three preprocessed datasets built on the Master branch.

✅ What you learned

• You can create and reference reusable utility functions inside your repository rather than rewriting them for every individual use.
• You can directly reference dataset RIDs in the input/output fields in the @transform_df decorator rather than the full Foundry file path.
