Recently, I worked on a deep learning project to classify chest X-ray images for pneumonia detection using Python and Keras. The challenge was to make the training process faster and more efficient, especially when dealing with thousands of medical images. That’s when I decided to use TPUs (Tensor Processing Units), powerful hardware accelerators that can … Read more >>
Working on a data validation project for a U.S.-based retail analytics company, I had to ensure that every input value in a Python script was a valid number before performing calculations. At first, it seemed like a simple task, just check if a variable is numeric. But as I dug deeper, I realized there are … Read more >>
While reviewing a large Python project for one of my clients in the USA, I encountered a tricky issue: a variable was being used before it was defined. This caused a NameError and broke the entire script. As a Python developer, I’ve learned that checking whether a variable exists before using it can save you … Read more >>
Recently, I was working on a project where I needed to process a list of student scores and classify them as Pass or Fail based on their marks. The challenge was to do this efficiently without writing multiple lines of code. That’s when I turned to Python list comprehension with if-else. It’s one of those … Read more >>
While working on a data-cleaning project for a retail company in the USA, I faced an interesting challenge. I had a Python dictionary containing customer IDs as keys and their email addresses as values.Some customers accidentally used the same email address for multiple accounts, and I needed to find all duplicate values in that dictionary. … Read more >>
Recently, while teaching a Python basics class, one of my students asked me how to print a simple number pattern like 1, 12, 123, and so on. It reminded me of my early coding days when I used to practice Python pattern programs to strengthen my logic and control flow skills. In this tutorial, I’ll … Read more >>
While working on a project that involved analyzing customer feedback data from different U.S. states, I had to unpack lists in Python multiple times. At first, it seemed simple, just extract values from a list and assign them to variables. But as my data became more complex, I realized how powerful Python’s list unpacking feature … Read more >>
Working on a Python web automation project, I needed to get the IP addresses of several websites dynamically. At first, I thought it would be as simple as sending a request and getting the IP, but I quickly realized that Python provides multiple ways to handle this task, each suitable for different use cases. In … Read more >>
Recently, I was working on a data visualization project that required representing customer data from different U.S. states in a 3D scatter plot. I wanted to make the visualization more meaningful by adjusting the marker sizes based on sales volume. That’s when I realized, many people don’t know how to effectively control marker size in a … Read more >>
I was working on a Python project where I needed to visualize a dataset that had three continuous variables, something like sales, profit, and region density across different states in the USA. While 2D scatter plots are great, I wanted to explore the data in a more interactive and visually appealing way. That’s when I … Read more >>
