Answer 1

Creating classes and instance of variables

class Student:
    # Creating a Class Variables
    perc_Raise = 1.05

    # Creating a constructor or a special method to initialize values
    def __init__(self,firstName,lastName,marks):
        self.firstName = firstName
        self.lastName = lastName
        self.email = firstName + "." + lastName +"@northalley.com"
        self.marks = marks

    def fullName(self):
        return '{} {}'.format(self.firstName,self.lastName)

    def apply_raise(self):
        self.marks = int(self.marks * self.perc_Raise)

Creating a two instance variable for a Student class

std_1 = Student('Mahesh','Gatta',62)
std_2 = Student('Saran','D',63)

print(std_1.fullName())
print(std_1.marks)

std_1.apply_raise()

print(std_1.marks)
print(std_1.email) 
print(std_1.__dict__)
print(std_2.fullName())
print(std_2.marks)

std_2.apply_raise()

print(std_2.marks)
print(std_2.email)
print(std_2.__dict__)

print(Student.__dict__)

Inheritance

class Dumb(Student):
    perc_Raise = 1.10

    def __init__(self,firstName,lastName,marks,prog_lang):
        super().__init__(firstName,lastName,marks)
        self.prog_lang = prog_lang

std_1 = Dumb('Suresh','B',51,'Python')

print(std_1.fullName())
print(std_1.marks)

std_1.apply_raise()

print(std_1.marks)
print(std_1.prog_lang)
