Generally, a flashcard is a learning tool that consists of a small card or piece of paper with information printed on one side. These are commonly used to aid in memorization and learning of facts, vocabulary, definitions, equations, or any other type of information that can be presented in a question-and-answer format. With the advancement of technology, flashcards have also been adapted into digital formats, such as mobile apps and online platforms, which provide additional features like multimedia content, spaced repetition algorithms, and progress tracking. There different approaches available in python to build the flash cards, let’s go through each ... Read More
The itertools is a module in the Python standard library that provides a collection of tools for efficient iteration and combination of iterables and as it is part of python standard library no need to perform any additional installations. It offers various functions that can be used to manipulate, combine, and iterate over iterables in different ways. The itertools.product() function is related to the itertools module, which is powerful tool for generating the cartesian product of multiple iterables. It takes one or more iterables as input and returns an iterator that produces tuples representing all possible combinations of the ... Read More
An octal number is a number expressed in the base-8 numeral system. It uses digits from 0 to 7. Octal numbers are commonly used in computer science and digital systems, especially when dealing with groups of three bits. In octal notation, each digit represents an increasing power of 8. The rightmost digit represents 8^0 (1), the next digit represents 8^1 (8), the next digit represents 8^2 (64), and so on. By combining these digits, octal numbers can represent positive integers. For example, the octal number 52 represents the decimal number as follows. (5 * 8^1) + (2 * 8^0) = ... Read More
What is PHP? PHP (Hypertext Preprocessor) is a widely used server-side scripting language for web development. It allows developers to embed code within HTML files, enabling the creation of dynamic web pages and interactions with databases. PHP is known for its simplicity, versatility, and extensive integration capabilities with popular databases. It offers a broad range of extensions and has a large community of developers, ensuring ample resources and support. PHP Program to Find the Number Occurring Odd Number of Times The concept of "Number Occurring Odd Number of Times" refers to finding a number in an array that ... Read More
Python socket is a set of modules used for socket programming, which enables communication between processes over IP networks. Sockets in Python provide the backbone for most network programming tasks. By importing relevant modules, we can write Python programs to create client and server programs for different types of network applications such as web scraping, file transfer, email clients, and chat applications. The "socket" module is the most important module of socket programming in Python. It provides different types of connection-oriented and connection-less sockets that implement specific protocol levels such as TCP, UDP, etc. TCP (Transmission Control Protocol) sockets TCP ...

A Dictionary is an unordered collection of data structure which stores the elements as key and value. It is mutable and in other programming languages Dictionaries are also known as associative arrays, hash maps, or hash tables. The key is the unique one and the values are of a single element or a list of elements with duplicates. A Dictionary can be created by using the curly braces {} or by using the built in function dict(). Let’s see an example of creating the dictionary in python. Example student = { 'name': 'Tutorialspoint', 'age': ... Read More
Progress bars in Python are visual indicators that provide feedback on the progress of a task or operation. They are useful for long-running processes or iterations where it's helpful to show how much work has been completed and how much is remaining. A progress bar typically consists of a visual representation, such as a horizontal bar or a textual representation, which dynamically updates to reflect the progress of the task. It also includes additional information like the percentage of completion, estimated time remaining, and any relevant messages or labels. The following are the purposes served by the progress bars in ... Read More
What is XAMPP? XAMPP is a software package that enables users to create a local web development environment on their computers. It includes the Apache web server, MySQL database, PHP scripting language, and Perl programming language. XAMPP simplifies the process of setting up a web server for testing and developing web applications, allowing users to work on their projects offline. It is widely used by developers to prototype and debug websites or web applications before deploying them to a live server. What is Database? A database is a structured collection of data organized and stored in ... Read More
Programming paradigm is a specific approach or style of programming that provides a framework for designing and implementing computer programs. It encompasses a set of principles, concepts, and techniques that guide the development process and the structure of the code. Different paradigms have different ways of solving problems, organizing code, and expressing computations. The below are the various programming paradigms available in python which makes the developer work easy and more efficient. Procedural Programming Procedural programming focuses on dividing a program into a set of procedures or functions. In Python, we can define functions to perform specific tasks and structure ...

The doomsday is also known as the doomsday of the week which is a specific day of the week that falls on the same date every year. The concept of the doomsday is based on the doomsday algorithm, which allows us to determine the day of the week for any given date. The doomsday algorithm was developed by mathematician John Horton Conway and is based on the idea that certain dates within each year fall on the same day of the week called the doomsday. The doomsday occurs on the following dates − January 3rd February 7th or 14th ... Read More
