Question 8: What is the role of the `sourcetype` module in the `scikit-learn` workflow?

In `scikit-learn`, the `sourcetype` module is used to classify the source of the data used for model training. This classification is crucial for selecting the appropriate algorithm and tuning the model's parameters. For example, you might use it to classify data as 'CSV', 'JSON', or 'Web' to choose the appropriate machine learning model.
