pandas.api.types.
is_sparse
(arr)[source]¶ Check whether an array-like is a pandas sparse array.
Parameters: arr : array-like
The array-like to check.
Returns: - boolean : Whether or not the array-like is a pandas sparse array.
Examples
>>> is_sparse(np.array([1, 2, 3])) False >>> is_sparse(pd.SparseArray([1, 2, 3])) True >>> is_sparse(pd.SparseSeries([1, 2, 3])) True
This function checks only for pandas sparse array instances, so sparse arrays from other libraries will return False.
>>> from scipy.sparse import bsr_matrix >>> is_sparse(bsr_matrix([1, 2, 3])) False
