# pandas.api.extensions.ExtensionArray._reduce

ExtensionArray._reduce(name, *, skipna=True, keepdims=False, **kwargs)

  Return a scalar result of performing the reduction operation.

  Parameters:
    namestr

      Name of the function, supported values are: { any, all, min, max, sum, mean, median, prod, std, var, sem, kurt, skew }.

    skipnabool, default True

      If True, skip NaN values.

    keepdimsbool, default False

      If False, a scalar is returned. If True, the result has dimension with size one along the reduced axis.

      Added in version 2.1: This parameter is not required in the _reduce signature to keep backward compatibility, but will become required in the future. If the parameter is not found in the method signature, a FutureWarning will be emitted.

    **kwargs

      Additional keyword arguments passed to the reduction function. Currently, ddof is the only supported kwarg.

  Returns:
    scalar
  Raises:
    TypeErrorsubclass does not define reductions

  Examples

      >>> pd.array([1, 2, 3])._reduce("min")
