Embedding Python code in a Tableau Prep flow

In the previous recipe, we prepared our machine to work with Python, using the Tableau Python server. In this recipe, we'll create a Tableau Prep flow and embed a Python script in it. This process is largely the same as we've practiced in the recipes for R. Using this script, we'll evaluate a dataset and flag anomalies, that is, outliers.

Getting ready

To follow along with this recipe, download the Sample Files 8.5 folder from this book's GitHub repository.

Important note

The Python scripts in this book serve to illustrate the process of integrating Python and Tableau Prep. Each dataset must be carefully analyzed prior to applying advanced functionality such as anomaly detection. The script referenced in this recipe is purely for illustration purposes and is not intended for real-world use.
