We'll learn how to split and join a string in Python in this article. Python defines strings as a collection of characters enclosed in one, two, or three quotations. When a string is split, it is divided into smaller strings using a specific delimiter. A set of one or more characters used to define a boundary is known as a delimiter. Anything could serve as a delimiter. The comma (, ), semicolon (;), tab (t), space (), and pipe (|) are the most widely used delimiters. Everywhere the specified delimiter appears in a given string, we must split it, and ... Read More

You will understand how to multiply every number in a list in Python in this article using various methods. A list is an ordered collection of values that are enclosed in square brackets. List contains values known as items that can be retrieved by their unique index. We'll create a function that multiplies each value in the list and outputs the result. The result of multiplying all the values is a single thing. For instance, the result will be 36 for the list [3, 2, 6]. We will go over the various methods for calculating the sum of all the ...

In this article, we will learn how to remove and print every third element or item from the list until it becomes empty using Python Program. First we create a list, the index of the starting address is 0 and the position of the first third element is 2 and need to traverse till the list becomes empty and another important work to do every time we have to find the index of the next third element and print the value and after that reduce the length of the list. Input-Output Scenario Following is the input and its output scenario ... Read More

In Java, we use inheritance to allow the creation of a hierarchical classification of classes and objects. As the name suggests, inheritance is the ability of a class to inherit members of another class. The class whose properties are inherited is called a superclass whereas the class that inherits a superclass is called a subclass. We use the extends keyword to inherit the class. There are several types of inheritance in Java such as single and multilevel. In this article, we will specifically explore the multiple inheritance. Multiple Inheritance in Java In the terminology of object-oriented programming, multiple inheritance is ... Read More

To find intersection of two lists in C#, use the Intersect() method.The following is our list 1.List list1 = new List(); list1.Add(2); list1.Add(3); list1.Add(5); list1.Add(7);The following is our list 2.List list2 = new List(); list2.Add(5); list2.Add(4); list2.Add(6); list2.Add(8);The following is the code to find the intersection of two lists in C#.Example Live Demousing System; using System.Collections.Generic; using System.Linq; using System.Text.RegularExpressions; namespace Demo {    public class Program {       public static void Main(String[] args) {          List list1 = new List();          list1.Add(2);          list1.Add(3);          list1.Add(5); ...

A MAC address of a device is a media access control address. It is a unique identifier assigned to a network.The MAC address technology is used by many technologies such as Ethernet, Bluetooth, Fibre Channel, etc.Here, we will use the following method to check for all the network interfaces on the computer.NetworkInterface.GetAllNetworkInterfacesFor this, the NetworkInterfaceType Enumeration is also used to specify the type of network interfaces.string addr = ""; foreach (NetworkInterface n in NetworkInterface.GetAllNetworkInterfaces()) {    if (n.OperationalStatus == OperationalStatus.Up) {       addr += n.GetPhysicalAddress().ToString();       break;    } } return addr;Above, we have used the ...

Extension methods are static methods, which are called as if they were instance methods on the extended type. With Extension methods, you can add methods to existing types without even creating a new derived type, recompiling, or modifying the original type.The following is the extension method we have created.public static int myExtensionMethod(this string str) {    return Int32.Parse(str); }Let us see an example wherein we have used extension method.Example Live Demousing System; using System.Text; namespace Program {    public static class Demo {       public static int myExtensionMethod(this string str) {          return Int32.Parse(str);     ...

The break statement terminates the loop and transfers execution to the statement immediately following the loop.When the break statement is encountered inside a loop, the loop is immediately terminated and program control resumes at the next statement following the loop.Let us see an example to learn how to work with break statement in while loop. The following code snippet terminates the loop using break statement.if (a > 15) {    break; }The following is the complete code.Example Live Demousing System; namespace Demo {    class Program {       static void Main(string[] args) {          /* local ...

It lets you modify the compiler's line number and (optionally) the file name output for errors and warnings. Let us see some examples. #line 100 "demo" int a; // CS0168 on line 100 int b; // CS0168 on line 101 int c; // CS0168 on line 102 As shown above the example reports three warnings associated with line numbers. The #line 100 directive forces the line number to be 100 and until the next #line directive, the filename will be reported as "demo”. Let’s see ... Read More

To access Array elements in a foreach statement, use the numeric index.Let’s say the following is our code.Example Live Demousing System; namespace ArrayApplication {    class MyArray {       static void Main(string[] args) {          int [] n = new int[10]; /* n is an array of 10 integers */          /* initialize elements of array n */          for ( int i = 0; i < 10; i++ ) {             n[i] = i + 100;          }       ...
