When I first started working with scientific data in Python, I quickly realized that linear plots often don’t tell the full story. Many real-world datasets, like population growth, financial data, or even earthquake magnitudes, span several orders of magnitude. That’s when I discovered the power of log-log plots in Matplotlib. A log-log plot transforms both … Read more >>
Recently, I was working on a project where I needed to compare large U.S. economic datasets. Some of the values ranged from very small fractions to extremely large numbers. When I plotted the data on a normal scale, the smaller values were almost invisible. That’s when I realized I needed log-log charts in Python Matplotlib. … Read more >>
When I first started working with Matplotlib loglog plots in Python, I quickly realized how powerful they are for visualizing data that spans several orders of magnitude. I’ve often needed to switch the logarithmic base from the default (base 10) to base 2, especially when working with data related to computer science, binary growth, or … Read more >>
I was working on a Python project where I had to create multiple plots in one figure. The issue was that my labels and titles were overlapping. This is a common problem many Python developers face, especially when working with multiple subplots. So, I decided to write this guide to share my experience. In this … Read more >>
TensorFlow has become one of the most widely used frameworks for deep learning and machine learning. The heart of TensorFlow is tensors and the operations we can perform on them. If you think of deep learning models as giant equations, then tensors are the variables carrying data, while tensor operations are the math and transformations that turn raw inputs … Read more >>
To swap two numbers in Python, use tuple unpacking: a, b = b, a. It is one line, works for any type (integers, floats, strings, list items) and needs no temporary variable. This guide shows that and the classic alternatives (a temporary variable, arithmetic and XOR), explains how swapping works inside a function, and includes … Read more >>
I was working on a Python project where I had to add several items to a shopping cart list at once. The challenge was simple, but I realized there are multiple ways to insert multiple elements into a Python list. Since I have been using Python for more than 10 years, I’ll walk you through … Read more >>
To check if a variable is None in Python, use the identity operator: if x is None:. To check that it is not None, use if x is not None:. Do not use == None or if not x for this: the first can be fooled by objects with a custom __eq__, and the second … Read more >>
In Python, a new line is the \n character. Put it anywhere inside a string and everything after it starts on the next line when you print it: Below I cover the /n mix-up, a Windows path that breaks by itself, joining lists, triple quotes and writing files. The screenshots are real runs on Python … Read more >>
Over the years of working with Python, I’ve often come across situations where I needed to reverse the order of items in a list. At first, it might sound like a simple task. But depending on the project, the way you reverse a list in Python can make a big difference in performance and readability. … Read more >>
