The task we are going to perform in this article is about how do you make an if statement in JavaScript that checks if a variable is equal to a certain word. What is an if...else statement When the condition in the if statement is true, a block of code will be executed. This is a form of conditional statement. The else block will be invoked if the condition is false. In if statements, truthy and falsy values are transformed to true or false. Syntax Following is the syntax for if else statement if (condition is true) { ... Read More
A cumulative histogram is a type of histogram that shows the cumulative distribution function (CDF) of a dataset. The CDF represents the probability that a random observation from the dataset will be less than or equal to a certain value. Cumulative histograms are useful when you want to compare the distribution of two or more datasets or when you want to visualize the proportion of data points that fall below a certain threshold. Plotly is a Python library for creating interactive and publication-quality visualizations. It is built on top of the D3.js visualization library and provides a wide range ... Read More
When line breaks should occur, they can be changed using the word-break property in CSS. Text line breaks typically only appear in specific locations, such as after a space or hyphen. Following is the syntax for word-break word-break: normal|break-all|keep-all|break-word|initial|inherit; Let’s dive into the article for getting better understanding on how can we prevent word breaking into different line in HTML table. Before that let’s have a quick view on the HTML table. HTML tables Web designers can organize information like text, images, links, and other tables into rows and columns of cells using HTML tables. The tag is ... Read More
Correlation analysis is a crucial technique in data analysis, helping to identify relationships between variables in a dataset. A correlation matrix is a table showing the correlation coefficients between variables in a dataset. It is a powerful tool that provides valuable insights into the underlying patterns in the data and is widely used in many fields, including finance, economics, social sciences, and engineering. In this tutorial, we will explore how to create a correlation matrix using Pandas, a popular data manipulation library in Python. To generate a correlation matrix with pandas, the following steps must be followed − ... Read More
Data visualization is an essential part of data analysis and communication, and Python offers many tools and libraries to create visually appealing and informative charts. Two such libraries are Plotly and pptx. Plotly is a powerful library for creating interactive charts, including bar charts, while pptx is a library for working with PowerPoint presentations. Creating a bar chart using Plotly is relatively easy. You can specify the data to be plotted, the type of chart, and the layout of the chart, and Plotly will generate a highquality chart that can be easily customised. Once the chart is created, you can ... Read More
SQLite is a popular lightweight and server less database management system used in many applications. It is known for its ease of use, small footprint, and portability. However, just like any other database, it is important to have a backup of your SQLite database to protect against data loss. Python is a powerful programming language that is widely used for various tasks including data processing and management. In this tutorial, we will explore how to create a backup of a SQLite database using Python. We will walk through the process of connecting to a SQLite database, creating a backup file, ... Read More
In Go programming language, field tags are metadata that can be attached to the fields of a struct type. These tags provide additional information about the field such as its name, data type, validation rules, etc. Field tags are used extensively in many Go libraries and frameworks, including database and web application frameworks. In this article, we will explore how to use field tags in the definition of a struct type in Go programming language. We will also discuss some common use cases of field tags and their benefits. What is a Struct Type in Go? A struct type is ... Read More
Based on the interface we have two types of applications CLI (Command Line Interface) applications and GUI (Graphical User Interface) applications. A command line application or, console application is the one which can be accessed from a shell or, command line through a text interface, these accepts inputs from the user in the text format. Unlike GUI Applications which provides a Graphical interface containing, buttons text boxes and icons, to the users to access the underlying application. Python is a popular programming language for developing CLI applications, though the process of packaging and distributing such applications is a bit ... Read More
Identifying colors in images is a task commonly performed in computer vision and image processing. It has a wide range of applications such as object detection, image segmentation, and image retrieval. In this article, we will see how to determine colors in an image using Python and OpenCV. Open CV is a popular computer vision library written in C/C++ with bindings for Python, OpenCV provides easy ways of manipulating color spaces. Open CV is open source and gives various algorithms useful in image processing. Before identifying colors in an image let us learn about some common image representation methods. ... Read More
Color spaces are different types of color modes, used in image processing and signals and system for various purposes. Open CV is a popular computer vision library written in C/C++ with bindings for Python, OpenCV provides easy ways of manipulating color spaces. Open CV is open source and gives various algorithms useful in image processing. In computer vision, colors are represented using color spaces. There are so many color spaces that are currently used in computer vision and image processing, each having its own unique characteristics and advantages. Some of the very common color spaces in image processing are ... Read More
