Solution
Here is the Python code for the Rectangle class as per your requirements:
class Rectangle:
def __init__(self, width=0, height=0):
self.width = width
self.height = height
@property
def width(self):
return self.__width
@width.setter
def width(self, value):
if not isinstance(value, int):
raise TypeError("width must be an integer")
if value < 0:
raise ValueError("width must be >= 0")
self.__width = value
@property
def height(self):
return self.__height
@height.setter
def height(self, value):
if not isinstance(value, int):
raise TypeError("height must be an integer")
if value < 0:
raise ValueError("height must be >= 0")
self.__height = value
def area(self):
return self.__width * self.__height
def perimeter(self):
if self.__width == 0 or self.__height == 0:
return 0
return 2 * (self.__width + self.__height)
This class has two private instance attributes: __width and __height. The @property decorator is used to make these attributes read-only, and the @width.setter and @height.setter decorators are used to validate and set the values of these attributes. The area and perimeter methods calculate and return the area and perimeter of the rectangle, respectively.
