• section 3.1 converts tdml df to pandas df just to print in sorted order.
• Link section to teradataml points to older teradataml version on docs.teradata -Output of all cells is missing.

Reviewer 1 suggestions:

• In section 3.1, no need to convert to pandas df. directly use sort() method of teradataml df
• Update the links from older doc to new one: https://docs.teradata.com/r/Enterprise_IntelliFlex_VMware/Teradata-Package-for-Python-User-Guide-17.20
• Recompile notebook to verify generated SQL queries.
