pandas.SparseDtype

class pandas.SparseDtype(dtype: Union[str, numpy.dtype, pandas.core.dtypes.base.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:

dtype : str, ExtensionDtype, numpy.dtype, type, default numpy.float64

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

fill_value : scalar, 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.
