Python is a versatile programming language that is popular among developers due to its simplicity and readability. In this blog post, we will cover some fundamental concepts of working with Python. Variables In Python, variables are used to store data values. Creating a variable is as simple as assigning a value to a label using the = assignment operator. Here’s an example: name = "Roger" You can also assign numeric values to variables:...
Discover the power of CSS Custom Properties, also known as CSS Variables, in modern browsers. These variables allow you to write better CSS by centralizing the values and reducing repetition and inconsistencies. One unique feature of CSS Variables is the ability to access and change their values programmatically using JavaScript. Introduction In recent years, CSS preprocessors like Less and SASS have gained popularity for their ability to nest selectors, provide easy imports, and introduce variables....
Debugging is an essential skill for programmers to overcome challenging situations and improve code efficiency. In Python, the built-in debugger pdb is available in the standard library, enabling developers to easily identify and fix errors. In this blog post, we will explore the key features of pdb and how to utilize it effectively in your Python projects. To start debugging your code, you can add breakpoints at specific locations using the breakpoint() function....
In Go, functions play a crucial role in structuring your code. They are blocks of code that have a specific name and contain a set of instructions. Understanding how to use functions effectively can greatly enhance your programming experience. In this article, we’ll explore the different aspects of functions in Go and how you can use them to your advantage. Defining Functions in Go Let’s start with the basics. In Go, functions are typically defined with a custom name....
In this tutorial, you’ll learn how to export functions and variables from a Svelte component. By exporting additional elements from a component, you can provide other components the ability to access and use them. Let’s dive in! To begin, you may already be familiar with importing a Svelte component into another component using the following syntax: <script> import Button from './Button.svelte'; </script> But what if you want to export something more than just the default export?...
In Go programming, pointers are an essential concept to understand. They allow you to directly access and manipulate the memory address of a variable. This blog post will guide you through the basics of using pointers in Go. Let’s start with an example. Suppose you have a variable called age with an initial value of 20. To get the pointer to this variable, you can use the ampersand (&) operator:...
In Python, introspection refers to the ability to analyze functions, variables, and objects to gather information about them. This ability is incredibly useful for understanding and debugging code. In this blog post, we will explore some of the key tools and techniques for introspection in Python. Getting Documentation with help() One of the simplest ways to gather information about a function, variable, or object is by using the help() function. This global function displays the documentation, if provided, in the form of docstrings....
Introduction In JavaScript, object destructuring is a powerful feature that allows you to extract specific properties from an object and assign them to individual variables. This can make your code more concise and readable by eliminating the need for repetitive object property access. How Object Destructuring Works Consider the following example: const person = { firstName: 'Tom', lastName: 'Cruise', actor: true, age: 57 }; To extract specific properties from the person object and assign them to variables, you can use object destructuring:...
Learn how to effectively use reactive statements in Svelte to listen for changes in component state and update other variables. In Svelte, you can easily track changes in component state and update related variables. Let’s take an example of a count variable: <script> let count = 0; </script> To update the count variable when a button is clicked, you can use the following code: <script> let count = 0; const incrementCount = () => { count = count + 1; } </script> {count} <button on:click={incrementCount}>+1</button> In order to listen for changes on the count variable, Svelte provides the special syntax $:....
