I am working on the file "Classes+and+Objects.ipynb".
The first task is:
Class Inheritance
Inheritance is a way of arranging objects in a hierarchy from the most general to the most specific. An object which inherits from another object is considered to be a subtype of that object.
We also often say that a class is a subclass or child class of a class from which it inherits, or that the other class is its superclass or parent class. We can refer to the most generic class at the base of a hierarchy as a base class.
Inheritance is also a way of reusing existing code easily. If we already have a class which does almost what we want, we can create a subclass in which we partially override some of its behaviour, or perhaps add some new functionality.
Can you write Python program for it?

# Simple Example of Inheritance

class Person:
    pass

# Parent class must be defined inside the paranthesis

class Employee(Person): 
    pass

e1 = Employee()
print(dir(e1))

class Person:
    
    def __init__(self,firstname,lastname):
        self.firstname = firstname
        self.lastname = lastname
        
    def __str__(self):
        return "[{},{}]".format(self.firstname,self.lastname)
    
class Employee(Person):
    pass

john = Employee('John','Doe')
print(john)

class Person:
    
    def __init__(self, firstname, lastname):
        self.firstname = firstname
        self.lastname = lastname
        
    def __str__(self):
        return "{},{}".format(self.firstname, self.lastname)
    
class Employee(Person):
    
    def __init__(self, firstname, lastname, staffid):
        super().__init__(firstname, lastname)
        self.staffid = staffid
        
    def __str__(self):
        return super().__str__() + ",{}".format(self.staffid)

john = Employee('Jack','Doe','12345')
print(john)
