6. Your First Day — Setting Up & Writing Real Code

⚙️ Step 1: Install VS Code

VS Code is your primary tool. Every serious developer uses it (or a close relative). It's free.

1. Go to code.visualstudio.com
2. Download the version for your operating system (Windows / Mac / Linux)
3. Install it and open it

When it opens, install these two extensions immediately (click the Extensions icon on the left sidebar or press Ctrl+Shift+X):

• Prettier — auto-formats your code so it always looks clean
• GitLens — shows Git history inside your editor

🐍 Step 2: Install Python

Python is the best first language because its syntax reads almost like English. Install it once and use it for everything in this guide.

Windows:

macOS:

Ubuntu / Linux:

Verify installation:

🖊️ Step 3: Your First Program

Create a new folder on your Desktop called my-first-project. Open it in VS Code (File → Open Folder). Create a new file called hello.py. Type this inside it:

Open the terminal in VS Code (Terminal → New Terminal or press Ctrl+`). Run the file:

You should see:

You just ran your first program. That's it. That's the loop: write code → run it → see the output → improve it.

🧪 Step 4: Build Something Real

Now extend your program to actually do something interactive. Create a new file called calculator.py:

Run it: python calculator.py. Try it with different numbers and operations. Then try breaking it — enter letters instead of numbers. See what happens. That error is the computer telling you what to fix next.

🔀 Step 5: Initialize Git

Before you write any more code, you need version control. Open the terminal in your project folder and run:

You've now saved a snapshot of your code. As you build more projects, always initialize Git from day one. It saves your history, lets you experiment safely, and is required for collaboration.

🗺️ Step 6: Your Roadmap From Here

You have now completed the Beginner's Guide. Here is your clear path forward:

1. Install Git and complete the Version Control track on VoidX. Do this now, before starting any technical track — you will need Git from your very first project.
2. Choose your first main track based on your goal (refer to Module 5). If unsure: start with Programming Core.
3. Build one small project per module — don't just answer the quizzes. Build something with each concept you learn.
4. Don't stop at tutorials. After finishing a track, immediately start a project that uses everything you learned.
5. Join the VoidX community. Ask questions. Share your projects. Code review each other's work. You learn fastest by explaining things to others.
