For columns containing dates, numbers or lists of numbers, values from inside a list are removed, nullifying the list itself when becoming empty.

​
Usage

The following example shows how the step can be used in a recipe.

Examples

Replace values outside of range [rangeLeft, rangeRight) with nulls:
extract_range(ds.price, {"rangeLeft": 200, "rangeRight": 800}) -> (ds.price_clipped)

​
Inputs & Outputs

The following are the inputs expected by the step and the outputs it produces. These are generally columns (ds.first_name), datasets (ds or ds[["first_name", "last_name"]]) or models (referenced by name e.g. "churn-clf").
​
col_in
column[date|number|list[number]]
required
A column to extract the range from.
​
col_out
column
required

​
