In Exercise 5.3 you created a notebook that targeted the PySpark language. When you hover over that notebook in Azure Synapse Analytics and click the ellipse (…), you will see the option to Export the Notebook. The supported formats are HTML (.html), Python (.py), LaTeX (.tex), and Notebook (.ipynb). The Jupyter notebook for Exercise 5.3 is in the Chapter05 directory on GitHub at https://github.com/benperk/ADE. There was a small change to the published Jupyter notebook versus the one you created in Exercise 5.3. The change was to break the code out from a single cell into three cells. Breaking the code into smaller snippets that are focused on a specific part of the ingestion, transformation, and storage is helpful because you can run each cell independently while testing.
