pandas.SparseDtype#

classpandas.SparseDtype(dtype=<class'numpy.float64'>,fill_value=None)[source]#

Dtype for data stored inSparseArray.

This dtype implements the pandas ExtensionDtype interface.

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, thisdepends ondtype.

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

The default value may be overridden by specifying afill_value.
