Spring Boot 4 provides a modern and efficient way to build REST APIs in Java. When combined with Spring Data JPA, Hibernate 7, and MySQL, it becomes a powerful stack for developing database-driven backend applications. In this tutorial, we will build a complete Spring Boot 4 REST API with MySQL [...]
Read MoreSpring Boot 4 and Hibernate 7 provide a powerful combination for developing modern database-driven Java applications. Spring Boot simplifies application configuration, while Hibernate handles object-relational mapping between Java objects and relational database tables. In this Spring Boot 4 + Hibernate 7 CRUD tutorial, we will build a complete CRUD application [...]

The following article describes some Common Ways to Create Web Applications in Python. Basically, there are several common ways to create web applications in Python, each with its own strengths and use cases. For instance, the following are some of the most popular approaches and frameworks. Django Django is a high-level, full-stack web framework for building robust and scalable web […]
The following article demonstrates How to Use Decorators in Python. Basically, decorators in Python are a powerful and flexible way to modify or enhance the behavior of functions or methods without changing their actual code. They are often used for tasks like logging, authentication, caching, and more. In fact, decorators are themselves functions that wrap other functions or methods. The […]
The following article describes How to Use Generators in Python. Basically, Generators in Python are a way to create iterators, which are objects that can be iterated (looped) over, but they don’t store the entire sequence of values in memory. Instead, they generate values one at a time on-the-fly, which can be very memory-efficient for large data sets or infinite […]
Here are 10 hands-on exercises on list slicing in Python along with their solutions. Exercise 1: Given a list numbers, create a new list containing the first three elements. Solution 1: Output: [1, 2, 3] Exercise 2: Given a list letters, extract the last two elements. Solution 2: Output: [‘d’, ‘e’] Exercise 3: Given a list my_list, create a new […]

The following article describes How to Implement Linear Regression With Multiple variables. Problem Statement Use the sklearn library to create a linear regression with multiple variables. Load a well known dataset split it into training and testing sets, and then train the model to predict a target variable based on one or more features. For instance, you can use the […]
The following program demonstrates How to Implement Gradient Descent Algorithm for Linear Regression. Problem Statement Implement the gradient descent algorithm for linear regression with one variable from scratch in vectorize form. Train a linear regression model using gradient descent to find the optimal coefficients (slope and intercept) for a given dataset. Also Plot the Gradient Descent. Solution The following code […]
The following program demonstrates How to Implement Linear Regression from Scratch. Problem Statement Implement a linear regression with one variable algorithm from scratch using Python. Given a dataset of X and Y values, create a linear regression model that predicts Y based on X without using any machine learning libraries like sklearn. Solution The following code shows a simple implementation […]
The following article demonstrates How to Perform Dataset Preprocessing in Python. Basically, dataset preprocessing is a crucial step before training a machine learning model. For this purpose, we need to handle the missing values and the categorical data. Further, we need to split the dataset into training and test datasets. The following program demonstrates how to perform descriptive statistics, handle […]
In this post I will discuss 30 MERN Stack Interview Questions and Answers. The MERN (MongoDB, Express.js, React, Node.js) stack is crucial in IT interviews because it assesses your proficiency in modern web development, JavaScript expertise, full-stack capabilities, database management with MongoDB, API development using Express.js, React skills for frontend development, and knowledge of Node.js for backend work. Also, it […]
