New Python Project: Build a Blackjack Game

We're super excited to share this new Python project. This one’s all about creating a fully functional Blackjack game with a GUI using PyQt5. It’s a perfect mix of game logic, Object-Oriented Programming (OOP), UI development, and event handling—all in one project.

This is an excellent way to level up your Python skills while building something interactive and fun. Plus, it makes for a great portfolio project to showcase Python and UI development expertise.

You can follow along as we build this, and we’ll be sharing all the code so you can tweak and improve it however you want!

How to Merge PDFs with Python

Want to build a fully functional PDF Merger app using Python? This step-by-step video tutorial (only about 30 minutes) walks you through creating a GUI-based tool with Tkinter and PyPDF2 to merge multiple PDFs effortlessly.

Specifically, the video covers:

• How to set up Tkinter for a user-friendly GUI

• How to use PyPDF2 to combine PDF files

• How to add and remove files dynamically before merging
