The output will look like this:

This output is interesting because it includes multiple values in this column, namely "Codes" and "Weight."
As we already have a separate "Weight" column, we must extract and retrieve only the codes from this combined column. Later, when we introduce "Format" wrangles, we will be able to split the values in this column.
