define inheritance code example

Example 1: inheritance

it is used to define relationship between two class, 
which a child class occurs all the properties and behaviours of a parent class. 
Provides code reusability.
Ex: in my framework I have a TestBase class which I store 
all my reusable code and methods. My test execution classes and 
elements classes will extend the TestBase in order to reuse the code.

Example 2: inheritance

class Employee():   def __init__(self, emp_id, salary):      self.emp_id = emp_id      self.salary = salary  def give_raise(self):      self.salary = self.salary * 1.05
