Assume the correct imports were made for Union and self-referencing classes such that this code listing contains no errors. For this diagram, you are not expected to have any constructor frames. 5 class Mul: lhs: Union[Div, Mul, int] rhs: Union[Div, Mul, int] 7 8. def eval(self) -> int: lhs = eval(self.lhs) rhs = eval(self.rhs) 10 11 12 return lhs * rhs 13 14 class Div: lhs: Union[Div, Mul, int] rhs: Union[Div, Mul, int] 15 16 17 18 def eval(self) -> int: lhs = eval(self.lhs) rhs = eval(self.rhs) 19 20 21 return lhs // rhs 22 def eval(e: Union[Div, Mul, int]) -> int: if isinstance(e, int): 23 24 25 return e 26 else: 27 return e.eval() 28 29 e = Div() 30 e.lhs = 6 31 e.rhs = Mul(O 32 e.rhs.lhs = 2 33 e.rhs.rhs 3 34 print(e.eval0)
