# pandas.Series.sparse

Series.sparse()

  Accessor for SparseArray from other sparse matrix data types.

  Provides methods and properties to work with the underlying sparse data in a Series or DataFrame. It allows accessing sparse-specific attributes such as fill value, density, and stored non-fill values, as well as converting to and from scipy sparse matrices.

  Parameters:
    data Series or DataFrame

      The Series or DataFrame to which the SparseAccessor is attached.

      >>> ser = pd.Series([0, 0, 2, 2, 2], dtype="Sparse[int]")
      >>> ser.sparse.density
      0.6
      >>> ser.sparse.sp_values
      array([2, 2, 2])
