The Global Interpreter Lock, commonly referred to as the GIL, has been one of Python’s most discussed features since its inception. The GIL is a mutex that protects access to Python objects, preventing multiple native threads from executing Python bytecode at once. While it simplifies memory management in CPython, the most widely used Python implementation, … Read more
Python is a versatile language that excels in many areas, but when it comes to taking full advantage of multi-core processors, it can sometimes feel like hitting a wall. This is where multiprocessing comes in—a powerful tool in Python’s arsenal that lets you break through the limitations of the Global Interpreter Lock (GIL) and unlock … Read more
Python is known for its simplicity and readability, but one feature it has historically lacked is a native switch case statement, commonly found in other programming languages like C, C++, and Java. Instead, Python developers often relied on a series of if-elif-else statements or dictionaries to emulate switch-case behavior. However, with the release of Python … Read more
Nuitka is a Python-to-C compiler that converts Python code into executable binaries. While Nuitka efficiently compiles Python scripts, incorporating data files such as images, audio, video, and additional Python files requires can be a little tricky. This guide outlines the steps to include various data files in a Nuitka standalone executable. Basic Setup for Nuitka … Read more
In this tutorial we will explore how to make the Tkinter Treeview Widget, “Editable”. In a previous tutorial, we wrote the following code to represent Product data in a Tabular format using the Treeview widget. But the problem with this approach, is that there is no way of editing the Table from the user’s perspective. … Read more
In this tutorial we will explore how to create a Table using the Treeview Widget in Tkinter. The Treeview widget is a versatile widget used to display hierarchical data in a tabular format.

Tkinter is not the most modern GUI library out there, and can be a bit lacking in certain features that are now common across modern GUIs. For example, a popular feature which we see in modern dropdowns (combo boxes) is that they are “searchable”. This means that if there are 30 options available in the … Read more
In this article we will show case a useful piece of code that was developed during a certain side-project of mine. The Project I was working on required an Interactive Scatter Plot that the user could interact it with in many ways. This includes features like being able to mass-select and highlight individual scatter points … Read more
In this tutorial, we will delve into the powerful combination of Pandas and Tkinter through the PandasTable library. PandasTable provides a convenient way to display and interact with pandas DataFrames in a Tkinter GUI. Prerequisites: You will also need to install the pandas and pandastable libraries. Run the following commands to do so: Creating Interactive … Read more
In this tutorial, we’ll walk through the process of creating a simple login form using PyQt6, a set of Python bindings for Qt, a powerful GUI toolkit. We’ll create a window with a title, username and password fields, and buttons for registration and login. Additionally, we’ll implement a basic login functionality to check if the … Read more
In this tutorial we will explore how to set up, install and use the SQLite3 Database in JavaScript. What is SQLite? SQLite is a lightweight, serverless, and embedded relational database management system (RDBMS) that is widely used, especially in applications with moderate data storage needs. SQLite offers several benefits that make it a popular choice … Read more
The following article demonstrates a useful trick in Tkinter to create multiple “screens” (e.g. a login screen, register screen, main page screen) within a single window! Instead of creating a new window for each screen, we will use a single tkinter window, which swaps dynamically between multiple “screens” (represented by frames). This is more efficient … Read more
