Single inheritance in python

 1) Single inheritance:

• If one base class and one derived class in a program called  “Single inheritance”.

Syntax:
1. class a:
             //Base class
   class b: public a
             //Derived class
   Object creation:
   object_name=Derived_class_name();
   object_name.function(parameter list);
Example:

1. class employee:#base class

       def get_data(self):#All function should have the self keyword for joining other fun

           id=input("Enter employee id:")

           name=input("Enter employee name:")

           depart=input("Enter employee department:")

           sal=int(input("Enter basic salary:"))

           return id,name,depart,sal

       def display(self,id,name,depart,sal):

           print("\tEmployee details")

           print("ID :",id)

           print("Name:",name)

           print("Department :",depart)

           print("Basic Salary : ",sal)

   class salary_cal(employee):#derived class

       def sal_cal(self,sal):

           if sal>=15000:

               sal+=5000

               print("Increased salary:5000")

               print("Net salary:",sal)

           elif sal>=1000 and sal<15000:

               sal+=3000

               print("Increased salary:3000")

               print("Net salary:",sal)

           else:

               sal+=1000

               print("Increased salary:1000")

               print("Net salary:",sal)

    

   #Object creation

   emp=salary_cal()

   empno,ename,deptno,sal=emp.get_data()

   emp.display(empno,ename,deptno,sal)

   emp.sal_cal(sal)
