Altair is a kind of statistical visualization library in Python. This library is based on vega and vega-lite javascript libraries. Moreover, we can visualize the data distribution in the form of a density plot in Python. These plots are useful whether we need to compare the variable distribution across the different groups or we need to visualize the distribution shape. The useful applications of density plots such as visualizing data shape, outlier detection, comparing distribution and model selection. The density plot is demonstrated in this article with the help of Python code. For better understanding, we are considering an example ... Read More
In this article, we will discuss how to generate a random one-time password (OTP). We will be using two modules in Python, namely the random and string modules, to accomplish this task. The random module provides relevant functions for generating random numbers, while the string module consists of numerous appropriate string constants. This application can be used for secure authentication or temporary access codes, catering to various aspects and requirements. We will present a few examples to illustrate the different approaches in which these programs can be applied. Let's take an example to demonstrate the computation. The following examples are ...

In this article, we will discuss how to compute the XOR of array elements that are divisible by a given number. The XOR (exclusive OR) is a binary operation that compares the bits of two operands. If the bits are different then it will return 1 whereas it returns 0 if the bits are the same. In this approach, we will use the property of XOR and apply this to this problem. The solution to this problem is shown with a relevant example. Let’s take an example to demonstrate the computation. Consider a simple example for understanding purposes, the array ... Read More
Jumbo GCD can be referred to find the Greatest Common Divisor (GCD) of a subarray with the maximum length of an array. The GCD is a set of positive integer numbers that divides all the numbers without having a remainder. We can find out the jumbo GCD subarray using two different approaches such as Brute force and Optimized approach using prefix sums. The solution of the jumbo GCD subarray is demonstrated in this article with relevant examples. The Brute force approach can be used to check all possible subarrays of the considering array and to calculate the GCD of an ... Read More
In this article, users would easily look up the first non-zero value in a row and obtain the corresponding column header. One example is showcased in this article that facilitates efficient solutions for working with data in Excel. By using the combination of the INDEX and MATCH functions in Excel, the provided formula allows the user to determine the column header associated with the first non-zero value in a specific row. By adjusting the ranges to match the data, the user can apply this formula across multiple rows or ranges, helping the user to analyze and process data based on ... Read More
Sometimes, in Excel the user wants to extract data for the provided task, the extraction will be from right to left. For example, if a cell contains data “Ana Ban” then the extracted string will be “Ban”. To demonstrate the formula used to accomplish this task will provide a simple example. All explanations are guided in a detailed stepwise manner. The first example guides the process of using the formula to perform the same task. Example 1: To pull or extract characters from right to left in a cell until a space is reached in excel by using the ... Read More
Protecting the workbook structure in Excel. It is an essential task that helps in accessing safeguarding the integrity of the user spreadsheet and prevents unauthorized modifications to the layout and organization. By implementing workbook structure protection, users can maintain the integrity of formulas, data validation settings, and other structural elements within their Excel workbook. This protection feature is particularly useful whenever the user needs to share a workbook with others or collaborate on a project while ensuring that the underlying structure remains intact. In this guide, we will explore the steps required to protect the workbook structure in Excel, ... Read More
The bounding rectangle of an object is a rectangle drawn around an object in the image. There are two methods to find the bounding rectangle in OpenCV − Straight Bounding Rectangle It is a straight rectangle as it does not consider the rotation of an object. It can be computed using the function cv2.boundingRect(). Its syntax is as follows − x, y, w, h = cv2.boundingRect(cnt) img = cv2.rectangle(img, (x, y), (x+w, y+h), (0, 255, 0), 2) Here, "cnt" is an array of the contour points. It returns the top-left coordinate (x, y) and width and height (w, h) ... Read More
In this article, the main objective is to guide the user through the process by using which printing X rows per page become easy for the user. This article describes two examples of how to perform the same task. The first example includes using the page break manually. The second example is based on the use of kutools. If will talk about the easiest guided example, is the second example that uses the kutools, as the number of steps performed to achieve the task is too less when compared with others. Example 1: To print X rows per page ... Read More
Printing worksheets without fill color in Excel ensures that the printed copies are clear and legible, without the distraction of background colors. Whether users have applied fill colors to cells or used conditional formatting, removing the fill color before printing can enhance the readability of the printed document. By following a few simple steps, the user can ensure that the available worksheets are printed without any background colors, allowing the data and content to take center stage. This helps maintain a professional and organized appearance when sharing or presenting your Excel worksheets in hard copy format. This explanation will allow ... Read More
