class_docstr: List methods for Series
class_docstr_tok: ["List","methods","for","Series"]
docstr: Returns boolean values indicating whether the specified scalar
  is an element of each row.
  
  Parameters
  ----------
  search_key : scalar
      element being searched for in each row of the list column
  
  Returns
  -------
  Series or Index
  
  Examples
  --------
  >>> s = cudf.Series([[1, 2, 3], [3, 4, 5], [4, 5, 6]])
  >>> s.list.contains(4)
  Series([False, True, True])
  dtype: bool
