pandas.SparseDtype

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

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
