Implement the Apartment class to inherit from the base Home class and contains all appropriate methods that need to be written for this derived class.

Answer 1

We can create a derived class Apartment, by specifying the name of base class, Home, along with the name of derived class.

1. Create a derived class Apartment
2. Define a constructor method
3. Call the constructor method of class, Home, and pass owner and address.
4. Set the rental price
5. Define getter and setter methods for rental_price.
6. Define __str__() function for Apartment class.
7. Create object of Apartment class.
8. Print owner, address and rental_price

class Home:
        def __init__(self, owner, address):
                self.__owner = owner
                self.__address = address
        def get_owner(self):
                return self.__owner
        def set_owner(self, owner):
                self.__owner = owner
        def get_address(self):
                return self.__address
        def set_address(self, address):
                self.__address = address
        def __str__(self):
                return "[ Owner : " + self.__owner + ", Address : " + self.__address + " ]"

class Apartment(Home):                                          # class Apartment inherits from class Home
        def __init__(self, owner, address, rental_price): # constructor method
                super().__init__(owner, address)        # call constructor of Home class
                self.__rental_price = rental_price      # set rental_price
        def get_rental_price(self):                     # getter method for rental_price
                return self.__rental_price                      # returns rental_price
        def set_rental_price(self, rental_price): # setter method for rental price
                self.__rental_price = rental_price      # sets rental_price
        def __str__(self):                                              # __str__() methods
                # returns a string representation of Apartment
                return "[ Owner : " + self.get_owner() + ", Address : " + self.get_address() + ", Rental Price : " +self.__rental_price + " ]"

apt1 = Apartment("abc", "address1", "1234")             # create an object of Apartment
print("Owner : ", apt1.get_owner())                             # print owner name
print("Address : ", apt1.get_address())                         # print address
print("Rental Price : ", apt1.get_rental_price())       # print rental price
print("Apartment : ", apt1)                                             # print apartment object, by default it calls __str__()

Screenshot:

class Home: def __init_(self, owner, address): self owner = owner self._address = address def get_owner(self): return self. __owner def set_owner(self, owner): self. __owner = owner def get_address(self): return self. __address def set_address(self, address): self._address = address def __str_(self): return "[ Owner : + self. __owner + ", Address : " + self._address + ]" class Apartment (Home): # class Apartment inherits from class Home def __init__(self, owner, address, rental_price): # constructor method super(). _init_(owner, address) # call constructor of Home class self.__rental_price rental_price # set rental_price def get_rental_price(self): # getter method for rental_price return self __rental_price # returns rental_price def set_rental_price(self, rental_price): # setter method for rental price self.__rental_price = rental_price # sets rental_price def _str_(self): str_() methods # returns a string representation of Apartment return "[ Owner : self.get_owner() + ", Address : + self.get_address() + ", Rental Price : # +self. _rental_price ]" apt1 = Apartment("abc", "address1", "1234") print("Owner : ", apt1.get_owner() print("Address : ", apt1.get_address) print("Rental Price : ", apt1.get_rental_price) print("Apartment : ", apt1) # create an object of Apartment # print owner name # print address # print rental price # print apartment object, by default it calls __str_o

Output:

Owner : abc Address : address1 Rental Price : 1234 Apartment : [ Owner : abc, Address : addressi, Rental Price : 1234 ]
