List is a datatype in Python which can be print as a list of comma-isolated values between square brackets. Advantage of using a list is that list items need not be of the same type. Creating a list is as simple as inserting different comma-separated values between square brackets. subject_list=
Range method returns values between start and stop, increasing by the value of step (defaults to 1)… range(start, stop, step) >>> for i in range (0, 10): … print(i) File “<stdin>”, line 2 print(i) ^ IndentationError: expected an indented block Lets fix this with a comma before print statement for

Interface in java is a model/prototype of a class. It has static constants and methods (without implementation). There can be only abstract methods in the java interface not method body. It is used to achieve abstraction and multiple inheritance in Java. It cannot be instantiated. Three reasons to use interface. They
Abstraction is to hide unnecessary details from the user and to show only relevant things/data to the user. Abstract class: Abstract class in Java contains the abstract keyword. If a class is declared abstract, it cannot be instantiated, means that you cannot create an object of an abstract class. Also, an abstract
Encapsulation is a technique in which you can bind your data and code together as a single unit. It’s a good approach to hide your data to make it safe from any modification. The best way to understand encapsulation is to look at the example of a medical capsule, where the
Inheritance is a concept in which one object interacts with the other object, where the properties of one class can be inherited by another class. It helps developer or programmer to reuse code and create a new bond between classes. Two things are involved in this process; Parent class (Base
For adding numbers of the same type we have to first define the variables. Like in the below code we define two variables of type int. int i=5; int j=10; int sum = i + j; System.out.println(sum); For adding numbers which have different types; int i=5; float j=10; float sum
Below programs display the pyramid of numbers based on user input // Library to import import java.util.Scanner; Scanner input = new Scanner (System.in); // for taking input from user System.out.println("Enter the Input Number that how many times do you want to get pyramid of numbers : "); int inputNumber =
