In Python, there are various ways to clear sub lists that drop outside an indicated run. The user will finish this assignment viably by leveraging list comprehension, iterative removal, or filtering and reproducing. List comprehension gives a brief approach by making an unused list based on given conditions. Iterative departure alters the introductory list by emptying sub lists that do not meet the run criteria. Filtering and duplicating strike an alter between memory viability and lucidness. In this article, the user will understand how to remove all sublists outside a given range using Python. Approach 1: Removing all Sublists outside a ... Read More
The list data structure holds elements of different datatypes like integers, strings, or float numbers. The elements that are once defined inside the list data structure that is within the square brackets cannot be changed. The digits which are defined inside the string value can be removed and later returns only the string value without digits. In this article, the digits are removed from every string defined in the list data structure and also provided with string manipulation techniques. Remove all digits from a list of strings The integers are removed from the string and the process is mentioned from ... Read More
When working with date objects in TypeScript, sometimes it's necessary to extract only the date and remove the time component from it. This can be useful when displaying dates in a user interface or comparing dates. In this tutorial, we will explore several ways to remove time from date in TypeScript. Syntax const dateWithoutTime = date.toLocaleDateString(); const dateWithoutTime = date.toISOString().split('T')[0]; The above is the syntax of two different typescript methods for removing time from date. The first method uses the toLocaleDateString() method. The second method uses this string () method. Example 1: Using the toLocaleDateString() Method const date = ... Read More
TypeScript is a powerful, statically typed superset of JavaScript that brings additional features and advantages to JavaScript development. Two commonly used types in TypeScript are any and object. In this tutorial, we will delve into the concepts of any and object in TypeScript and explore how they can be used in various scenarios. We will provide clear syntax explanations, code examples, and their corresponding outputs to help beginners grasp these concepts effectively. The any Type The any type is a special type in TypeScript that allows variables to hold values of any type. It provides flexibility by bypassing static type ... Read More
Data representation is crucial in software development, and it is essential to present data in a user-friendly way with the increasing demand for web-based applications. Text boxes are one of the ways to do so. Text boxes provide an easy way to display data to users in a structured and presentable way. This tutorial will provide a comprehensive guide on using text boxes in TypeScript to show data effectively. We will cover what text boxes are, provide syntax and algorithms for working with text boxes, and give multiple examples to illustrate how to use text boxes. What are Text Boxes ... Read More
TypeScript is a superset of JavaScript that includes all the features of JavaScript and more. It provides additional features like static typing, interfaces, classes, and modules to help developers write more robust and maintainable code. In this article, we will discuss why you should use TypeScript for developing web applications and how it can benefit you, with examples. Static Typing One of the primary benefits of TypeScript is static typing. Static typing means variables, function parameters, and function return types must be defined before the code is compiled. This makes it easier for developers to catch errors before the code ... Read More
Lambda expressions offer a succinct and expressive means of defining functions in TypeScript and are versatile enough to be utilized as class methods, object properties, and callbacks in higher-order functions. This tutorial aims to delve into the syntax of lambda expressions, highlight their advantages over conventional functions, and provide guidance on how to use lambda expressions in TypeScript effectively. What are Lambda Expressions? Lambda expressions, commonly referred to as arrow functions, were first introduced in ECMAScript 6 and have gained widespread usage in contemporary JavaScript and TypeScript code. These expressions provide a succinct syntax for defining functions in both languages. ... Read More
Quick Sort is a Divide and Conquer algorithm. In this algorithm, we elect a pivot element and then partition the array around the pivot element. The two partitions are such that one part contains elements all lower than the pivot element and the other part contains elements all higher than the pivot element. Similarly, each part is further partitioned around a pivot selected in each part and this process is executed until one single element is reached. Choosing a Pivot A pivot can be chosen in an array as follows − A random pivot. Rightmost or leftmost element as ... Read More
The structured query language (SQL) commands deal with the manipulation of data present in the database that belongs to the DML or Data Manipulation Language. This includes most of the SQL statements.Examples of DMLThe examples of DML in the Database Management System (DBMS) are as follows −SELECT − Retrieve data from the database.INSERT − Insert data into a table.UPDATE − Update existing data within a table.DELETE − Delete records from a database table.Syntax for DML CommandsThe syntax for the DML commands are as follows −INSERTInsert command is used to insert data into a table.The syntax for INSERT command is as ...

Introduction The epoch is the date and time relative to which a computer's clock and timestamp values are determined. Epoch time is commonly used in computer systems to represent a point in time. It is typically represented as a single integer value, which represents the number of seconds that have elapsed since the epoch. In SQL, you can convert an epoch time value to a date by using the to_timestamp() function. This function converts an epoch time value (which is typically stored as a BIGINT or INT data type) to a timestamp with time zone value. The resulting timestamp value ... Read More
