How to Use GitHub Copilot to Write Your First Program in Under 2 Hours

If you’re a beginner trying to dive into coding, the sheer volume of resources and tools can be overwhelming. You might find yourself spending more time sifting through tutorials than actually writing code. Enter GitHub Copilot — a tool that leverages AI to help you code faster. In this guide, I’ll show you how to use GitHub Copilot to write your first program in under 2 hours. Yes, really.

What You Need to Get Started

Prerequisites

1. GitHub Account: You’ll need to create a GitHub account if you don’t have one already.
2. Visual Studio Code (VS Code): Download and install VS Code, the code editor we'll use.
3. GitHub Copilot Subscription: GitHub Copilot is $10/month after a free trial. Make sure you have a subscription or at least access to the trial.
4. Basic Understanding of Programming Concepts: Familiarity with variables, loops, and functions will help, but I’ll guide you through the basics.

Step-by-Step Guide to Writing Your First Program

Step 1: Install GitHub Copilot in VS Code

• Open VS Code.
• Go to the Extensions view by clicking on the Extensions icon in the sidebar or pressing Ctrl+Shift+X.
• Search for “GitHub Copilot” and click Install.
• Once installed, sign in with your GitHub credentials.

Step 2: Create a New File

• Create a new file in VS Code and name it hello_world.py. This will be our first program.
• As you start typing, GitHub Copilot will suggest code snippets based on what you write.

Step 3: Write Your First Code

• Start by typing a comment: # This program prints Hello, World!
• Then type print( and notice how Copilot suggests completing the line. Accept the suggestion by pressing Tab.

Expected Output:

# This program prints Hello, World!
print("Hello, World!")

Step 4: Run Your Code

• Open a terminal in VS Code (`Ctrl + ``).
• Type python hello_world.py and hit Enter.
• You should see Hello, World! printed in the terminal.

Step 5: Experiment with Copilot

• Now, let's add some functionality. Type a comment like # Calculate the sum of two numbers and then start typing the code.
• Watch how Copilot suggests the complete function. For example:

Expected Output:

# Calculate the sum of two numbers
def sum(a, b):
    return a + b

result = sum(5, 3)
print(result)

Step 6: Troubleshooting Common Issues

• Error Messages: If you encounter errors, check your syntax. Copilot is not perfect and may suggest incorrect code.
• No Suggestions: If Copilot isn't suggesting anything, try typing a more specific comment or function name.

What's Next?

Once you’ve completed your first program, try building upon it. Add more functions, or even try creating a simple calculator. The possibilities are endless!
