Object Oriented Programming.

Python is Object Oriented Programming:

Overview of object Oriented Programming:

Class

Classes are defined by the users. The class provide basic strucuture for an object , it consists of data memebers and method member that are used byinstance (object) of the class.

Data member:

A variable define in either a class or an object, it holds the data associated with the class or object.

Instance Variable:

A variable that is define in a method. Its scope is within the object that defien its.

Class Variable:

A variable that is define in the class and can be used by all the instance of that class.

Instance:

A object is instance of a class.

Method:

Methods are the function that are define in the definition of the class and used by various instance of the class.

Function Overloading:

A function define more than one time with different behaviour is known as Function overloading. The operation performed by these functions are different.

Inheritance

A class A that can use the characteristics of another class B is said to be derived class that i.e class inherited from B . This process is known as Inheritance.

Encapsulation:

Encapsulation is an important features in Object oriented programming . The wrapping of data and function in single unit is called data Encapsulation. This method is also called data hiding.

Polymorphism

Poly means many therefore the term Ploymorphism mean that object of the class can have many different form to respond in diffrent ways for any message of action.

Introduction to Python.

What is python? Python is an object-oriented programming language created by Guido Rossum in 1998. If you just beginning your programming career, python suits you best. With python you can do everything from GUI developement, web application, Machine learning, IOT, Game Developement etc. so it is general purpose high level programming language. It is very easy language,it is good for beginners. It is case sensitive language. Python is Dynamically Typed, Write less code do more. Introduction Easy to Learn and Use Python is easy to use and learn, it is user friendly and high level programming language. Expressive language Pyton language is more expressive means that is more understand and readable. Unique style Python is an interpreted language i.e interpreter execute the code line by line at a time . This makes debugging easy and thus suitable for beginners. Cross Platform Language Python can run equally on different platform such as windows, Linu...

Conditional Statement Decision making of an anticipation of condition occuring by execution of program and dpecific action is taken according to condtion. Following is a general form of typical decision making structure found in most programming language. Python programming language uses any non-zero or non-null value as true and if it is either zero or null then it is assume false value. if Condition: In python the block of statement is executed if the condition is true. Syntax if (condition): Block(s) Example var1=100 if var1: print('i got an true value') print(var1) output i got an true value 100 Question: Write a program that prompt user to enter two integer values, print the message "equal" if both entered value are equal a=int(input("Enter first number")) b=int(input("Enter second number")) if a==b: print("equal") output Enter fir...
