I keep coming back to CSV files whenever I need to move data between systems. They are the simplest way to represent tabular data as plain text, and every system from databases to spreadsheets can read them. If you have…
I’ve parsed more text files than I can count over the years – logs, configs, CSV exports, API responses saved to disk. The job is always the same: open the file, read the content, turn raw text into something my…
I first played Flappy Bird on my phone and immediately wanted to build it myself. The original game is deceptively simple – tap to flap, avoid pipes, rack up a score. But once I started building it with Python and…
I ran into the least cost transportation problem again last week, this time when a small manufacturing client needed help cutting their shipping costs. They had three plants shipping to five distribution centers, and every route had a different price…

I ran into this exact expression while solving a palindrome problem on a coding challenge platform. The line int(a[::-1]) looked cryptic at first glance — three colons, a negative step, wrapped in int(). But once I broke it down, it…
I have seen the knapsack problem show up in quite a few technical interviews. It is one of those problems that feels tricky at first but becomes much clearer once you see the recursive pattern underneath. In this tutorial, I…
Python classes are the foundation of every non-trivial program. After years of using them daily, I have a good sense of what actually helps someone grasp this material quickly and what just confuses people. This guide is the article I…
I keep coming back to base64 whenever I’m working with APIs, JWT tokens, or any system that needs to safely transmit binary data as text. The other day I needed to decode a webhook payload that came in as a…
