pandas.SparseDtype

class pandas.SparseDtype(dtype=<class 'numpy.float64'>, fill_value=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
timedelta64 pd.NaT

The default value may be overridden by specifying a fill_value.

Attributes

fill_value The fill value of the array.
kind The sparse kind.
name A string identifying the data type.
names Ordered list of field names, or None if there are no fields.
type The scalar type for the array, e.g.
subtype
