如何调用函数计算面积周长

一个名为countandPrint的函数，参数为inst,功能是

（1）调用inst.info()输出传入对象的信息
测试数据C1(120)

你这里info没定义啊

class Graph:
    def __init__(self, length, width):
        self.length = length
        self.width = width
        
    def getArea(self):
        area = self.length * self.width
        return area

    def getPerimeter(self):
        perimeter = 2 * (self.length + self.width)
        return perimeter

    def info(self):
        area = self.getArea()
        perimeter = self.getPerimeter()
        print("Length: ", self.length)
        print("Width: ", self.width)
        print("Perimeter: ", perimeter)
        print("Area: ", area)
class Rectangle(Graph):
    def __init__(self, width, height):
        super().__init__(width, height)
        self.width = width
        self.height = height

    def getArea(self):
        area = self.width * self.height
        return area

    def getPerimeter(self):
        perimeter = 2 * (self.width + self.height)
        return perimeter

    def info(self):
        area = self.getArea()
        perimeter = self.getPerimeter()
        print("Width: ", self.width)
        print("Height: ", self.height)
        print("Perimeter: ", perimeter)
        print("Area: ", area)
class Circle(Graph):
    def __init__(self, radius):
        super().__init__(radius, radius)
        self.radius = radius

    def getArea(self):
        area = 3.1416 * self.radius ** 2
        return area

    def getPerimeter(self):
        perimeter = 2 * 3.1416 * self.radius
        return perimeter

    def info(self):
        area = self.getArea()
        perimeter = self.getPerimeter()
        print("Radius: ", self.radius)
        print("Perimeter: ", perimeter)
        print("Area: ", area)

def countandPrint(inst):
    inst.info()

R1 = Rectangle(90, 80)
C1 = Circle(120)

countandPrint(R1)
countandPrint(C1)
