Over my 10+ years of working with Python, I’ve often come across situations where I needed to calculate the absolute value of a number but couldn’t use the built-in abs() function. At first, this might sound unusual; after all, abs() is quick and reliable. But in real-world projects, especially coding interviews, algorithm challenges, or restricted … Read more >>
Recently, I was working on a project where I had to quickly retrieve the first key from a Python dictionary. At first, it sounded simple, but when I dug deeper, I realized that dictionaries don’t behave exactly like Python lists. The challenge was that dictionaries are unordered collections in older versions of Python. But starting … Read more >>
When I first started coding in Python more than a decade ago, one of the simplest yet most common tasks I had to perform was building strings dynamically. I often had an empty string and wanted to add characters to it one by one. While it sounds simple, there are multiple ways to achieve this … Read more >>
I was working on a project where I had to validate data stored in a Python dictionary. The challenge was simple: I needed to check if a dictionary contained specific keys or values. At first, I thought there might be a built-in function like dict.contains(). But soon, I realized Python doesn’t have such a function. … Read more >>
When I was working on a data visualization project for a client in the USA, I had to prepare multiple charts for a business dashboard. The issue was that the axis labels and titles were getting cut off because the margins at the bottom and right side were too tight. That’s where the subplots_adjust() function … Read more >>
I was working on a project where I needed to visualize multiple datasets in 3D using Python.The challenge was to compare them side by side without switching between multiple plots. That’s when I turned to Matplotlib subplots in 3D. This feature allows me to create multiple 3D axes in the same figure, which makes it … Read more >>
As a developer, I was working on a Python project where I had to visualize multiple datasets side by side using subplots. Each subplot had its own scale and color mapping. The challenge I faced was how to add a separate colorbar to each subplot in Matplotlib. At first, I tried to use a single … Read more >>
Recently, I was working on a Python data visualization project where I had to create multiple charts in one figure. The issue I faced was that the subplots were too close to each other, making the labels and titles overlap. It looked messy and unprofessional. If you have worked with Matplotlib in Python, you might … Read more >>
I’ve often needed to display multiple images side by side. Whether I was preparing a report for a client or analyzing satellite data for a project, one tool always came to my rescue: Matplotlib. Matplotlib is one of the most powerful Python libraries for data visualization. What many people don’t realize is that it is … Read more >>
I first started working with Matplotlib in Python, and I often struggled with subplot layouts. Sometimes my charts would overlap, or the spacing just didn’t look professional. After more than 10 years of experience as a Python developer, I’ve realized that two powerful tools can completely change the way you design subplots: Gridspec and grid … Read more >>
