How can I pass through specific columns without transforming them?

Hey, I’m working on a project and I’m a bit stuck. I need to pass through certain columns without having them transformed. I heard about using something called ColumnTransformer, but I’m not quite sure how it works. Could anyone explain how I can pass through specific columns without transforming them, maybe with an example?

One way to pass through columns is to use the passthrough parameter in a Scikit-learn ColumnTransformer object. Here’s an example:

In this example, we use the 'passthrough' string for the transformer object in the tuple corresponding to the columns that we want to pass through. We also include a StandardScaler transformer for the other columns. The resulting transformed data will include the original ‘sepal length (cm)’ and ‘sepal width (cm)’ columns.
