In this tutorial, I will explain how to print the contents of a file in Python. As a developer working on various projects, I came across a scenario where I needed to print the content of a file, which made me explore more about this topic. I will cover different methods to read and print … Read more >>
In this tutorial, I will explain how to copy files to another directory in Python. During a project for one of my clients, I had the requirement to organize files and back up data. Copying files offers various ways to accomplish this efficiently. Let’s get into the various methods and best practices for copying files … Read more >>
You have a folder full of sales reports, and you want a small script that reads the files, totals each region, and creates a clean summary. With Python, you can usually get that first useful version running quickly. With Java, you may write more setup code, but you gain a strong foundation for building larger, … Read more >>
To write multiple lines to a file in Python, open the file with open(“file.txt”, “w”) and call f.write(“\n”.join(lines) + “\n”), or f.writelines() with each line ending in “\n”. writelines() does not add line breaks for you, which is the most common surprise. This guide compares write(), writelines(), print(file=…) and pathlib, shows how to append lines, … Read more >>
I was working on a data visualisation project where I had to analyse customer purchase data across different U.S. states. I wanted to represent the data in a 3D scatter plot using Python Matplotlib so that I could easily see the relationship between income, spending, and satisfaction levels. While creating the plot was easy, I … Read more >>
Working on a data visualization project where I needed to show how data points move in 3D space over time. I wanted a smooth 3D scatter animation that could rotate and update dynamically. The challenge was that while Matplotlib makes it easy to plot static 3D graphs, animating them isn’t as straightforward. So, I decided … Read more >>
Working with 3D medical images like CT scans has become increasingly important in healthcare AI. From my experience as a Python Keras developer, 3D image classification requires a different approach than typical 2D images due to the volumetric nature of the data. In this tutorial, I’ll guide you through building a 3D convolutional neural network … Read more >>
In my years of developing data visualizations with Python, I have realized that the default settings are rarely perfect. Often, the default tick labels are just too small to read on a high-resolution screen or a printed report. I have spent a lot of time tweaking plots for presentations, and I found that adjusting the … Read more >>
To create 3D subplots in Matplotlib, pass projection=”3d” to the subplot you want in 3D: fig.add_subplot(1, 2, 2, projection=”3d”), or make every subplot 3D with plt.subplots(2, 2, subplot_kw={“projection”: “3d”}). You can mix 2D and 3D subplots in one figure and use any 3D plot type (surface, wireframe, scatter, line) in each. This guide shows each … Read more >>
When working with Keras in Python, especially for deep learning projects, you might encounter the error: ModuleNotFoundError: No Module Named ‘keras.utils.vis_utils’. This frustrating error typically appears when trying to visualize neural network models. In this tutorial, I will walk you through several proven methods to resolve this error based on my decade-plus experience as a … Read more >>
