JSON (JavaScript Object Notation) is a popular format for data exchange between systems. It is a lightweight, text−based, and easy−to−parse format that has become a standard for data exchange over the internet. However, JSON does not provide any order for the elements in the data structure. While this may not be an issue in most cases, there are situations where the order of the elements is important. On the other hand, OrderedDict is a subclass of the built−in dict class in Python, which maintains the order of the keys in the dictionary. The order is determined by the order in ... Read More

When it comes to automation, be it to setup your computer on start-up or to farm coins on a clicker game, it becomes essential to simulate mouse movements and clicks. And what better way to do this than use Python! For performing this particular task of automating or simulating your mouse movement, we will be using Python’s mouse library that has various methods and functionalities to help simulate your mouse on your computer. Now that you know what we will be working with, let us get started! Getting Started Firstly, we need to install the mouse library. Since this library ... Read More

Creating a simple alarm clock is one of the basic projects that can help you understand the basics of time manipulation, running system commands, playing audio files and other such essential topics. And, in this tutorial, we will be learning how to build one. For this, we will be working with the PyGame module to play the audio file and the datetime module to get the current system time. Alright, let us get started then! Getting Started For playing the audio file, we will be using the PyGame module. This module does not come pre-packaged with Python. So, we’ll be ... Read More

We’ve all wanted to add additional effects to our presentation or to a video. These effects help us in better present our product or helps increase user experience. And in this tutorial, you will learn how to implement the snow effect using the arcade module. You can use this in your games to create a snow drizzle or a rain drop effect. You can even go ahead and set it up as a screen timeout effect. That being said, let us get started! Getting Started Throughout this tutorial, we will be using the arcade module that helps users create game ... Read More

Now that you know what we are dealing with, let us get started. Getting Started It’s better to download errbot in a virtual environment rather than directly installing it. Firstly, we have to download and install the errbot library. We’ll be using the pip package manger to do this. ... Read More

Numpy is a popular Python library used for numerical computing and scientific computing, providing a powerful array object for handling large and multi−dimensional arrays. However, when it comes to machine learning, deep learning, and neural networks, PyTorch is a widely used library that provides an efficient and flexible platform for building and training these models. While Numpy arrays and PyTorch tensors are similar in many ways, they have different properties and methods, which makes it necessary to convert a Numpy array to a PyTorch tensor when using PyTorch for machine learning applications. In this article, we will explore the process ... Read More

Remote access to computers has become increasingly important, especially in today's work from home environment.

Python is a popular programming language used in a wide range of applications, including network programming. In this article, we will explore how to connect to a WiFi network using Python. Connecting to a WiFi network using Python can be useful in situations where you need to automate the process of joining a network, such as in a headless system or in a situation where manual intervention is not possible. Python provides several libraries that can be used to interact with WiFi networks, and we will explore some of them in this article. We will start by looking at the ... Read More

In data analysis and manipulation, dealing with dates and times is a common requirement. The Pandas library in Python provides powerful tools for working with datetime values. In this article, we will explore the process of converting datetime values to date−only format in a Pandas DataFrame. When working with datetime values, it is often necessary to extract specific components, such as the year, month, day, or time, for further analysis or visualisation. However, in some cases, we may only be interested in the date portion of the datetime object, excluding the time information. Converting datetime values to date−only format can ... Read More
