Usage of Asterisks in Python
Python programming language uses both * and ** in different contexts. In this article, we will explore how these operators are used and their practical applications. As an Infix Operator When * is used as an infix operator, it performs mathematical multiplication on numbers. Let's see examples with integers, floats, and complex numbers ? # Integers x = 20 y = 10 z = x * y print(z) # Floats x1 = 2.5 y1 = 5.1 z1 = x1 * y1 print(z1) # Complex Numbers x2 = 4 + 5j y2 = 5 + ...
Read MoreStatistical Thinking in Python
Statistical thinking is fundamental for machine learning and AI. Since Python is the language of choice for these technologies, we will explore how to write Python programs that incorporate statistical analysis. In this article, we will create graphs and charts using various Python modules to analyze data quickly and derive insights through visualization. Data Preparation We'll use a dataset containing information about various seeds. This dataset is available on Kaggle and has eight columns that we'll use to create different types of charts for comparing seed features. The program below loads the dataset and displays sample rows. ...
Read MoreLast-child and last-of-type selector in SASS
SASS provides advanced selectors that extend CSS functionality, including :last-child and :last-of-type pseudo-selectors. These selectors help target specific elements based on their position within parent containers. Last-child Selector in SASS The :last-child selector targets the last child element within a parent container, regardless of the element type. It applies styles to the final element and all its nested children. Syntax .parent-element :last-child { /* CSS properties */ } Example 1: Basic Last-child Selection This example demonstrates selecting the last child element within a container − ...
Read MorePredicting Customer Churn in Python
Customer churn refers to customers leaving a business. Predicting churn helps businesses identify at-risk customers and take preventive actions. This article demonstrates how to build a machine learning model to predict telecom customer churn using Python. Dataset Overview We'll use the Telecom Customer Churn dataset which contains customer information like demographics, services, and churn status. Let's load and examine the data ? import pandas as pd # Loading the Telco-Customer-Churn.csv dataset # Dataset available at: https://www.kaggle.com/blastchar/telco-customer-churn data = pd.read_csv('Telecom_customers.csv') print("Dataset shape:", data.shape) print("First few rows:") print(data.head()) The output shows the dataset structure ? ...
Read MoreHow to rotate shape loader animation using CSS?
In this article, we'll see how to rotate shape loader animation using CSS. Loading animations of different shapes is an essential part of a web app as it helps users stay engaged while they wait for a website to load. One popular type is the rotating shape loader, where a shape spins continuously until the web page is fully loaded. Moving ahead, we are going to use different approaches to rotate shape loader animations with various examples. Syntax .loader { animation: rotation duration timing-function iteration-count; } @keyframes rotation { ...
Read MoreHow to design initial letter of text paragraph using CSS?
The CSS ::first-letter pseudo-element is used to style the first letter of a text paragraph. This allows you to apply specific styles to the initial letter of the first line of a block-level element, making it stand out with different font size, color, or style. Syntax selector::first-letter { property: value; } Common Properties The following properties are commonly used with ::first-letter − PropertyDescription font-sizeSets the size of the first letter colorChanges the color of the first letter floatCreates drop cap effect line-heightControls vertical spacing marginAdds space around the ...
Read MoreFraud Detection in Python
Fraud detection is a critical application of machine learning where we analyze historical transaction data to predict whether a new transaction is fraudulent. In this tutorial, we'll build a fraud detection system using credit card transaction data, applying a decision tree classifier to identify suspicious transactions. Preparing the Data We start by loading and exploring our dataset to understand its structure and features. The credit card fraud dataset contains anonymized features (V1-V28) obtained through PCA transformation, along with Time, Amount, and Class columns ? import pandas as pd # Load the credit card dataset # ...
Read MoreHow to display a link using only CSS?
To display a link using CSS, we can style anchor elements with various properties to control their appearance and behavior. CSS allows us to customize how links look, whether they appear active or disabled, and how users interact with them.

Read MoreHow to create animated banner links using HTML and CSS
We can create animated banner links using HTML and CSS to make advertisements and call-to-action buttons more engaging. HTML provides the banner structure while CSS handles styling and animations to draw user attention and increase click-through rates. Syntax a { animation: animation-name duration timing-function direction iteration-count; } @keyframes animation-name { 0% { /* initial styles */ } 50% { /* middle styles */ } 100% { /* final styles */ } } Example: Animated Banner Link The ...
Read MoreHow to create Area Chart using CSS
An area chart is a graphical representation of data that displays quantitative information by filling the area between a line and the axis. Using CSS custom properties and the clip-path property, we can create visually appealing area charts directly in the browser without external libraries. Syntax .area-chart { clip-path: polygon(x1 y1, x2 y2, x3 y3, x4 y4); --start: value; --end: value; } Key Components To create an area chart, we need these essential elements − CSS Custom Properties − Variables ...
