When I first started working with Python over a decade ago, one of the earliest lessons I learned was the importance of naming things properly. Whether it’s a variable, a function, or a class, the names we choose, known as identifiers in Python, play a big role in how readable and maintainable our code becomes. … Read more >>
When I first started working with Python, one of the simplest yet most essential operations I learned was subtraction. Whether it was subtracting two numbers, calculating differences between lists, or subtracting user inputs, subtraction has always been a core part of Python programming. In this tutorial, I’ll walk you through how to create a Python … Read more >>
While working on a Python automation project that processed client reports from multiple states across the USA, I needed a way to stop my Python script safely when certain conditions were met. At first, I thought I could just use a simple break or return statement, but those only work inside loops or functions. I … Read more >>
Deep learning models can be powerful, but they are also notoriously hard to interpret as they train. Without proper monitoring, you may not realize that your model is stuck, overfitting, or wasting resources. Imagine training for hours only to find that the model never improved because of a bad learning rate. This is where TensorBoard … Read more >>
Over the past decade of working with Python, I’ve often needed to clean or preprocess text data. Whether it’s cleaning messy CSV files, preparing user input for machine learning, or formatting data for reports, removing unwanted characters from strings is something I do almost every week. In this tutorial, I’ll show you five practical methods … Read more >>
I was working on a Python project where I needed to send data from a backend API to a web client. The data was stored in a dictionary, but I couldn’t send it directly; I needed to convert that dictionary into a string first. If you’ve ever faced a similar situation while developing in Python, … Read more >>
Recently, while teaching Python to a group of data enthusiasts in New York, one of my students asked me how to find an Armstrong number using recursion in Python. At that moment, I realized that while many people know how to check an Armstrong number using loops, very few understand how to do it recursively, … Read more >>
Neural networks may sound intimidating the first time you hear about them, but once you break them down into inputs, hidden layers, and outputs, they become surprisingly approachable. In this tutorial, you’ll learn exactly how to build your first neural network in TensorFlow, a powerful library for machine learning and deep learning. By the end, you’ll … Read more >>
TensorFlow provides immense flexibility for developers, but with that flexibility comes complexity. Those who have worked on training deep learning models know that things rarely work perfectly on the first attempt. The training loss might refuse to decrease, tensors might not match expected shapes, or a model that performs well during training might fail in … Read more >>
Prototyping has become one of the most important stages in the journey from concept to deployment in machine learning. TensorFlow, one of the most widely used deep learning frameworks, offers multiple levels of abstraction. Among them, Keras stands out with a simple, modular, and high-level API that lets you move from idea to working solution in minutes. … Read more >>
