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
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()
import math
class PlaneGraphics:
def __init__(self, x, y):
self.x = x
self.y = y
def area(self):
pass
def perimeter(self):
pass
class Rectangle(PlaneGraphics):
def __init__(self, x, y, width, height):
super().__init__(x, y)
self.width = width
self.height = height
def area(self):
return self.width * self.height
def perimeter(self):
return 2 * (self.width + self.height)
class Ellipse(PlaneGraphics):
def __init__(self, x, y, a, b):
super().__init__(x, y)
self.a = a
self.b = b
def area(self):
return math.pi * self.a * self.b
def perimeter(self):
return 2 * math.pi * math.sqrt((self.a ** 2 + self.b ** 2) / 2)
# 测试代码
rect = Rectangle(0, 0, 5, 10)
print("Rectangle area:", rect.area())
print("Rectangle perimeter:", rect.perimeter())
ellipse = Ellipse(0, 0, 3, 5)
print("Ellipse area:", ellipse.area())
print("Ellipse perimeter:", ellipse.perimeter())
基于new bing部分指引作答:
可以使用Python中的类(class)来定义平面图形的父类和子类,具体代码如下所示:
import math
class PlaneGraphics:
def __init__(self, color):
self.color = color
def get_color(self):
return self.color
class Rectangle(PlaneGraphics):
def __init__(self, color, length, width):
super().__init__(color)
self.length = length
self.width = width
def get_area(self):
return self.length * self.width
def get_perimeter(self):
return 2 * (self.length + self.width)
class Ellipse(PlaneGraphics):
def __init__(self, color, major_axis, minor_axis):
super().__init__(color)
self.major_axis = major_axis
self.minor_axis = minor_axis
def get_area(self):
return math.pi * self.major_axis * self.minor_axis
def get_perimeter(self):
a = self.major_axis/2
b = self.minor_axis/2
return 2 * math.pi * math.sqrt((a ** 2 + b ** 2) / 2)
在上述代码中,我们定义了一个PlaneGraphics
父类作为所有平面图形的基类,并且有一个颜色属性。然后,我们定义了Rectangle
子类和Ellipse
子类分别作为长方形和椭圆的具体实现。
每个子类都扩展了PlaneGraphcis
父类,并增加了自己特定的属性(例如长方形的长度和宽度,椭圆的半长轴和半短轴)。此外,每个子类还实现了get_area
和get_perimeter
方法来计算图形的面积和周长。
请注意,在使用这些类时,可以通过创建相应的对象并调用其方法来操作和访问属性。例如:
rectangle = Rectangle("红色", 10, 5)
print(rectangle.get_color())
print(rectangle.get_area())
print(rectangle.get_perimeter())
ellipse = Ellipse("蓝色", 8, 4)
print(ellipse.get_color())
print(ellipse.get_area())
print(ellipse.get_perimeter())
上述代码将创建一个红色的长方形对象,并打印出颜色、面积和周长。然后,它还创建一个蓝色的椭圆对象,并打印出相应的属性值。
