code: def kwargs_factory(

      """
      Generates a list of dictionaries as follows:
  
          - each string in `keys` is a key
          - the elements of `values` are mapped through a cartesian product and then mapped to keys
  
      Parameters
      ----------
      keys:
          List of dict keys.
      values:
          List of dict values. See examples for result.
  
      Returns
      -------
          A list of dictionaries with keys specified in `keys`. Each element has as keys one of the elements of the
          cartesian product of the elements of `values`.
  
      Examples
      -------
          # >>> values, keys = [[1], [1, 2]], ['a', 'b']
          # >>> result = kwargs_factory(keys, values)
          # >>> print(result)
