pandas.api.types.is_sparse

pandas.api.types.is_sparse(arr)

Check whether an array-like is a 1-D pandas sparse array.

Check that the one-dimensional array-like is a pandas sparse array. Returns True if it is a pandas sparse array, not another type of sparse array.

Parameters

arrarray-like

Array-like to check.

Returns

bool

Whether or not the array-like is a pandas sparse array.

Examples

Returns True if the parameter is a 1-D pandas sparse array.

>>> is_sparse(pd.arrays.SparseArray([0, 0, 1, 0]))
True
>>> is_sparse(pd.Series(pd.arrays.SparseArray([0, 0, 1, 0])))
True

Returns False if the parameter is not sparse.

>>> is_sparse(np.array([0, 0, 1, 0]))
False
>>> is_sparse(pd.Series([0, 1, 0, 0]))
False

Returns False if the parameter is not a pandas sparse array.

>>> from scipy.sparse import bsr_matrix
>>> is_sparse(bsr_matrix([0, 1, 0, 0]))
False

Returns False if the parameter has more than one dimension.
