Print objects of a class in Python
An object is the part of the Object Oriented Language (OOPs), which is an instance of the class. The class is the blueprint or template that specifies the methods and properties of that given class. When we create an object of a class, it contains all the set of instance methods and variables that are related to that particular object Using __str__ method We have two methods namely, __str__ or __repr__ in python which automatically calls the string and used to print the object with the detail view about it. Following is the syntax for using the __str__ method. ...
Read MoreProgram to print window pattern
Python is one of the most popular and efficient programming language which helps the developers to write and execute the code very easily and faster. It provides several methods, packages, modules and libraries to develop the code within no time and with less complexity. A window can be a square or a rectangle or a triangle with having a plus sign or without a plus sign, in the middle. In order to print the window pattern using the python language let’s see an example and understand. Example In this example, we will create a window in the rectangle without ...
Read MoreProgram to Print K using Alphabets
Python is used to print different patterns easily within less time as per the user requirement. In the same way, we can print the letter K using the alphabets available in the English language. Example In this example we will create the letter K by using the K alphabet. The below is the code. string="" j = 7 i = 0 for Row in range(0, 10): for Col in range(0, 10): if (Col == 1 or ((Row == Col ...
Read MoreProgram to check if a string contains any special character
Python helps us to develop code as per the developer requirement and application. It provides multiple modules, packages, functions and classes which makes the code more efficient. Using python language, we can check if a string contains any special character or not. There are several ways to check the string for the specials characters in it, let’s see one by one. Using a Regular Expression The re module in Python provides support for regular expressions, which are patterns used to match character combinations in strings. The regular expression pattern [^a−zA−Z0−9\s] matches any non−alphanumeric character (excluding whitespace) in the string. The ...
Read MoreHow to move a Torch Tensor from CPU to GPU and vice versa?
A torch tensor defined on CPU can be moved to GPU and vice versa. For high-dimensional tensor computation, the GPU utilizes the power of parallel computing to reduce the compute time.High-dimensional tensors such as images are highly computation-intensive and takes too much time if run over the CPU. So, we need to move such tensors to GPU.SyntaxTo move a torch tensor from CPU to GPU, following syntax/es are used −Tensor.to("cuda:0") or Tensor.to(cuda)And, Tensor.cuda()To move a torch tensor from GPU to CPU, the following syntax/es are used −Tensor.to("cpu")And, Tensor.cpu()Let's take a couple of examples to demonstrate how a tensor can be ...
Read MoreHow can I apply an offset on the current time in Python?
Whenever you want to add or subtract(apply an offset) to a date/time, use a datetime.datetime(), then add or subtract datetime.timedelta() instances. A timedelta object represents a duration, the difference between two dates or times. The timedelta constructor has the following function signature − datetime.timedelta([days[, seconds[, microseconds[, milliseconds[, minutes[, hours[, weeks]]]]]]]) Note − All arguments are optional and default to 0. Arguments may be ints, longs, or floats, and may be positive or negative. You can read more about it here − https://docs.python.org/2/library/datetime.html#timedelta-objects Example An example of using the timedelta objects and dates − import datetime old_time = datetime.datetime.now() print(old_time) ...
Read MoreAdd key-value pair in C# Dictionary
To add key-value pair in C# Dictionary, firstly declare a Dictionary.IDictionary d = new Dictionary();Now, add elements with KeyValuePair.d.Add(new KeyValuePair(1, "TVs")); d.Add(new KeyValuePair(2, "Appliances")); d.Add(new KeyValuePair(3, "Mobile"));After adding elements, let us display the key-value pair.Example Live Demousing System; using System.Collections.Generic; public class Demo { public static void Main() { IDictionary d = new Dictionary(); d.Add(new KeyValuePair(1, "TVs")); d.Add(new KeyValuePair(2, "Appliances")); d.Add(new KeyValuePair(3, "Mobile")); d.Add(new KeyValuePair(4, "Tablet")); d.Add(new KeyValuePair(5, "Laptop")); d.Add(new KeyValuePair(6, "Desktop")); d.Add(new KeyValuePair(7, "Hard Drive")); ...
Read MoreXOR Linked List – A Memory Efficient Doubly Linked List
Linked List The linked list is a linear data structure containing elements called nodes. Each node consists of two main components: data (payload of that node) and a pointer to the next node in the list. They are simple and efficient to use providing easy allocation and deallocation of memory. Doubly Linked List Doubly linked list is a special type of linked list which again consists of a basic element called nodes. Each node consists of three main components: data (payload of that node), a pointer to the previous node of the sequence and a pointer to the next ...
Read MoreSort numbers stored on different machines
In today’s world with a large amount of data and interconnected systems, a vast amount of data is created and stored across various machines. One challenging challenge is to sort this data stored across multiple devices. Sorting being a fundamental operation in computations is used for optimal retrieval, search and analysis of data. But with distributed systems and various interconnected machines, this task of sorting becomes difficult and important. Problem Statement Given an array containing N linked lists that depict N different machines. Each of these linked lists contains some variable number of numbers in sorted order. The task is ...
Read MorePrint unique rows in a given Binary matrix
In computer science, binary matrix holds a very strong position containing a lot of information as the data is depicted using 0’s and 1’s which is the language of computers. In binary matrix, unique row refers to a row that is not identical to any other row in the matrix. Each unique row contains unique information that is not present anywhere else in the matrix except the row itself. Discovering these unique rows give information about relationships between rows, patterns in the matrix and identification of critical elements. Problem Statement Given a binary matrix mat[] containing 0’s and 1’s. The ...
