classpandas.arrays.BooleanArray(values,mask,copy=False)[source]#

Array of boolean (True/False) data with missing values.

This is a pandas Extension array for boolean data, under the hoodrepresented by 2 numpy arrays: a boolean array with the data anda boolean array with the mask (True indicating missing).

BooleanArray implements Kleene logic (sometimes called three-valuelogic) for logical operations. SeeKleene logical operations for more.

To construct an BooleanArray from generic array-like input, usepandas.array() specifyingdtype="boolean" (see examplesbelow).
