How Can I Move Beyond Basic Python Projects?

Hey everyone! I just started a Computer Science degree at WGU and have completed one class so far. I've been coding for about a year as a hobbyist, but I've really started taking it seriously over the past three months. I've created some fun projects in Python like a text-based adventure game, a personal finance tracker that reads from a CSV file, and a simple IOT program for tracking expiry dates in my fridge. I even dabbled in Lua for Roblox game development!

However, I feel like I've hit a wall. I've got the basics down—like classes, lists, and loops—but I'm struggling with importing libraries and understanding documentation when it comes to expanding my projects. I want to take my work beyond command-line applications and create real software. Although I found the basics tough initially, things started clicking for me after some time, but it feels like there's a steep learning curve now.

I'm looking for advice on how to learn the frontend side of things and how to connect it with the backend work I've already done. I prefer learning by doing, but I'm at a loss about where to start with UI/UX. I've tried using Streamlit for a UI but got really frustrated after hours of trying without success.

I'm passionate about programming and want to turn this into a career, even considering an unpaid internship for the experience. But I'm worried that my current projects aren't competitive enough to land one. I really appreciate any advice, encouragement, or even critical feedback you can offer!
