code: def astuple(obj, *, tuple_factory=tuple):
      
  
      if not _is_dataclass_instance(obj):
          raise TypeError("astuple() should be called on dataclass instances")
      return _astuple_inner(obj, tuple_factory)
docs: Return the fields of a dataclass instance as a new tuple of field values.
  
      Example usage::
  
        @dataclass
        class C:
            x: int
            y: int
  
      c = C(1, 2)
      assert astuple(c) == (1, 2)
  
      If given, 'tuple_factory' will be used instead of built-in tuple.
      The function applies recursively to field values that are
      dataclass instances. This will also look into built-in containers:
      tuples, lists, and dicts.
