pandas.SparseDtype

class pandas.SparseDtype(dtype: Union[str, numpy.dtype, ExtensionDtype] = <class 'numpy.float64'>, fill_value: Any = None)

Dtype for data stored in SparseArray.

This dtype implements the pandas ExtensionDtype interface.

New in version 0.24.0.

Parameters

dtypestr, ExtensionDtype, numpy.dtype, type, default numpy.float64

The dtype of the underlying array storing the non-fill value values.

fill_valuescalar, optional

The scalar value not stored in the SparseArray. By default, this depends on dtype.

dtype	na_value
float	np.nan
int	0
bool	False
datetime64	pd.NaT
timedelta64	pd.NaT

The default value may be overridden by specifying a fill_value.
