Answer:

Provided are two Python programs for the problem solution. Find appropriate, the one that suits you for better understanding

Explanation:

FIRST CODE

class Person:

def __init__(self, name, address, number):

self.name = name

self.address = address

self.number = number

def Name(self):

return self.name

class Customer(Person):

def __init__(self, name, address, number,custNumber,needMailList):

Person.__init__(self,name, address, number)

self.custNumber = custNumber

self.needMailList = needMailList

x = Person("Marge", "Delhi","1245632541")

y = Customer("Homer", "Mumbai", "32514789","11",False)

print(x.name)

print(y.name)

print(x.Name())

SECOND CODE

class Person:

   def __init__(self, name, address, tel_num):

       self.__name = name

       self.__address = address

       self.__tel_num = tel_num

class Customer(Person):

   def __init__(self, name, address, tel_num, cus_num=0, mail=True):

       Person.__init__(self, name, address, tel_num)

       self.__cus_num = cus_num

       self.__mail = mail

   def set_name(self, name):

       self.__name = name

   def set_address(self, address):

       self.__address = address

   def set_tel_num(self, tel_num):

       self.__tel_num = tel_num

   def set_cus_num(self, cus_num):

       self.__cus_num = cus_num

   def set_mail(self, mail):

       self.__mail = mail

   def get_name(self):

       return self.__name

   def get_address(self):

       return self.__address

   def get_tel_num(self):

       return self.__tel_num

   def get_cus_num(self):

       return self.__cus_num

   def get_mail(self):

       return self.__mail

def main():

   n = eval(input('Enter number of customers: '))

   lst = []

   for x in range(n):

       name = input("Enter name: ")

       address = input("Enter address: ")

       cusNum = int(input("Enter customer number: "))

       telNum = input("Enter telephone number: ")

       mail = bool(input("Enter mail id: "))

       c = Customer(name, address, telNum, cusNum, mail)

       lst.append(c)

   for x in range(n):

       print(lst[x].get_name(), lst[x].get_address(), lst[x].get_tel_num(), lst[x].get_cus_num(), lst[x].get_mail())

main()
