python计算面积问题

Question

怎么定义平面图形父类PlaneGraphics。和定义长方形子类Rectanale和随圆形子类Eclipse

Answer 1

代码如下 , 如有帮助给个采纳谢谢

import math


class PlaneGraphics:
  def __init__(self, shape):
    self.shape = shape

  def calculate_area(self):
    pass

  def display_shape_and_area(self):
    print(f"Shape: {self.shape}")
    print(f"Area: {self.calculate_area()}")


class Rectangle(PlaneGraphics):
  def __init__(self, shape, width, height):
    super().__init__(shape)
    self.width = width
    self.height = height

  def calculate_area(self):
    return self.width * self.height


class Ellipse(PlaneGraphics):
  def __init__(self, shape, major_axis, minor_axis):
    super().__init__(shape)
    self.major_axis = major_axis
    self.minor_axis = minor_axis

  def calculate_area(self):
    return math.pi * self.major_axis * self.minor_axis


# 举例
rectangle = Rectangle("Rectangle", 4, 6)
rectangle.display_shape_and_area()

ellipse = Ellipse("Ellipse", 3, 10)
ellipse.display_shape_and_area()
