I remember working on a project for a photography firm in Chicago where we had to restore thousands of grainy vintage photos. I used a convolutional autoencoder in Keras to automatically remove digital noise while preserving sharp details. Load the Dataset using Keras I usually start by loading a standard dataset like MNIST because it … Read more >>
Handwriting recognition is one of those projects that truly feels like magic when you first get it right. I remember the first time I built a model that could actually read my scribbled notes; it changed how I viewed automation. In this guide, I will show you how to build a robust handwriting recognition system … Read more >>
As a developer, I have spent a lot of time wrestling with clocks. Mast APIs and databases prefer “UNIX time”—the number of seconds since January 1, 1970—because it is a simple integer that avoids timezone confusion. However, as humans, we prefer reading dates like “December 25, 2025, 10:00 AM,” which is why we use Python … Read more >>
I have found that “empty” variables are the leading cause of crashes. I remember once debugging a Python script that processed IRS tax forms. A single “None” value in a list of deductions caused the entire payroll run to fail. Checking if a variable is not empty in Python is a fundamental skill that separates … Read more >>
In my ten years of architecting Python solutions for data-heavy firms in Chicago, I have seen developers stumble over one specific concept: the “empty” number. In Python, strings can be empty (“”) and lists can be empty ([]), but a float is a numeric type. It always holds a value, even if that value represents … Read more >>
Python Turtle appears simple at first glance, but it offers powerful ways to explore graphics programming while improving logical thinking. Many interviewers use it to test coding fundamentals, creativity, and problem-solving skills. Understanding how to control the turtle, manipulate colors, and handle events can demonstrate practical Python knowledge that stands out in technical interviews. This … Read more >>
To print 2 decimal places in Python, we can use the Python str.format() method with “{:.2f}” as string and float as a number. Then call the Python print(), it will print the float with 2 decimal places.
In my experience of writing Python code for data analytics firms, I have hit the same wall many times. You try to combine a piece of text with a decimal number, and Python throws a “TypeError.“ It is a classic beginner mistake, but even seasoned pros occasionally forget that Python is a strongly typed language. … Read more >>
In my Python development journey, few things are as frustrating as seeing a massive wall of red text in your terminal. One of the most common errors I encounter, especially when setting up new environments for US-based fintech projects, is the “command errored out with exit status 1.“ It usually happens when you are trying … Read more >>
Over the past ten years of building financial applications in Python, I have come to realize one thing: users dislike reading raw numbers. Seeing a value like 10000000 on a dashboard is frustrating. It takes a second or two for the brain to process whether that is ten million or one hundred million. We rely … Read more >>
