1. Unsupervised Learning: Customer Segmentation

1.1 Extracting Customer IDs

We can obtain customer IDs from a clustered DataFrame using the following code:

clustered_df['CustomerID'].values

These customer IDs can be used to extract names and email addresses from a customer database. For example, the resulting array might look like this:

array([125, 129, 131, 135, 137, 139, 141, 145, 147, 149, 151, 153, 155,
       157, 159, 161, 163, 165, 167, 169, 171, 173, 175, 177, 179, 181,
       183, 185, 187, 189, 191, 193, 195, 197, 199], dtype=int64)
