IP (Internet Protocol) Address is an address of your network hardware. It helps in connecting your computer to other devices on your network and all over the world. An IP Address is made up of numbers or characters.All devices that are connected to an internet connection have a unique IP address which means there’s a need of billions of IP addresses. This requirement is fulfilled by the new IP version IPv6.Private IP AddressA private IP address is the address of your device connected on the home or business network. If you have a few different devices connected to one ISP ... Read More

The WebClient class provides common methods for sending data to or receiving data from any local, intranet, or Internet resource identified by a URI.The WebClient class uses the WebRequest class to provide access to resources. WebClient instances can access data with any WebRequest descendant registered with the WebRequest.RegisterPrefix method.DownloadString Downloads a String from a resource and returns a String.If your request requires an optional header, you must add the header to the Headers collectionExampleIn the below example we are calling the url "https://jsonplaceholder.typicode.com/posts"The example is then deserialized to User arrayFrom the user array we are printing the first array valueExampleclass ...

The [] operator is called an indexer.An indexer allows an object to be indexed such as an array. When you define an indexer for a class, this class behaves similar to a virtual array. You can then access the instance of this class using the array access operator ([ ]).Indexers can be overloaded. Indexers can also be declared with multiple parameters and each parameter may be a different type. It is not necessary that the indexes have to be integers.Example 1static void Main(string[] args){    IndexerClass Team = new IndexerClass();    Team[0] = "A";    Team[1] = "B";    Team[2] ...

There are many ways to check whether internet is connected to a machine in C# or not. Make use of System.Net namespace which provides common methods for sending data to and receiving data from a resource identified by a URI. The WebClient or HttpClient class provides common methods for sending data to or receiving data from any local, intranet, or Internet resource identified by a URI. Here in the below example we have used (OpenRead)Returns the data from a resource as a Stream.Checks by hitting the url "http://google.com/generate_204" if success return true else false.The below example runs in the loop ...

IntroductionPandas have a dual selection capability to select the subset of data using the Index position or by using the Index labels. Inthis post, I will show you how to "Select a Subset Of Data Using lexicographical slicing".Google is full of datasets. Search for movies dataset in kaggle.com. This post uses the movies data set from kaggle.How to do it1. Import the movies dataset with only the columns required for this example.import pandas as pd import numpy as np movies = pd.read_csv("https://raw.githubusercontent.com/sasankac/TestDataSet/master/movies_data.csv", index_col="title", usecols=["title", "budget", "vote_average", "vote_count"]) movies.sample(n=5)titlebudgetvote_averagevote_countLittle Voice06.661Grown Ups 2800000005.81155The Best Years of Our Lives21000007.6143Tusk28000005.1366Operation Chromite05.8292.

IntroductionPandas have a dual selection capability to select the subset of data using the Index position or by using the Index labels. Inthis post, I will show you how to “Select a Subset Of Data Using Index Labels” using the index label.Remember, Python dictionaries and lists are built-in data structures that select their data either by using the index label or byindex position. A dictionary’s key must be a string, integer, or tuple while a List must either use integers (the position) or sliceobjects for selection.Pandas have .loc and.iloc attributes available to perform index operations in their own unique ways. ...

This article is aimed at developers who want to find the largest or smallest items with Python. I will show a few methods touse and will conclude the best method for you.Method – 1: Slice approach on a ListIf you are simply trying to find the single smallest or largest item i.e N = 1, it is faster to use min() and max().Let us begin by generating some random integers.import random # Create a random list of integers random_list = random.sample(range(1, 10), 9) random_listOutput[2, 4, 5, 1, 7, 9, 6, 8, 3] FINDING THE SMALLEST & LARGEST ITEM (N=1) # ...

ProblemYou need to identify the most frequently occurring items in a sequence.SolutionWe can use counter to keep track of the items in a sequence.What is a Counter ?The “Counter” is a mapping that holds an integer count for each key. Updating an existing key adds to its count. This Objectis used for counting the instances of hashable objects or as a multiset.The “Counter” is one of your best friends when you are performing data analysis.This object has been present in Python for quite some time, and so for a lot of you, this will be a quick review.We will start ...

Depending on the flexibility and complexity required, we can split a string on multiple delimiters in several ways such as using Python's re.split() method, which is a combination of various string methods. Some of the commonly used approaches to split strings on multiple delimiters. str.replace() and str.split() re.split() Method translate() ... Read More

We are given with a string of characters and the task is to calculate the count of pairs having both the elements as vowels. As we know there are five vowels in English alphabet i.e. a, i, e, o, u and other characters are known as Consonants.Input − string str = "tutorials point”Output − Count the pairs of vowels in the given string are: 2Explanation − From the given string we can form pairs as (t, u), (u, t), (t, o), (o, r), (r, i), (i, a), (a, l), (l, s), (s, p), (p, o), (o, i), (i, n) and ...
