How to Use AI Tools to Write Your First 100 Lines of Code

Starting your coding journey can feel daunting, especially if you're a complete beginner. You might ask yourself, "How do I even write my first line of code?" Luckily, in 2026, AI coding tools have evolved to make this process smoother and more accessible than ever. In this guide, I’ll walk you through practical tools and steps to help you write your first 100 lines of code using AI.

Time Estimate and Prerequisites

Time: You can finish this in about 3 hours.
Prerequisites:

• A computer with internet access
• A basic understanding of what programming is (no prior experience required)
• A willingness to experiment and learn

Step-by-Step Guide to Using AI Coding Tools

1. Choose Your Programming Language

Before diving in, decide on a programming language. For beginners, Python is often recommended due to its readability and simplicity. JavaScript is another good choice if you’re interested in web development.

2. Set Up Your Environment

You’ll need an Integrated Development Environment (IDE) or a code editor. Some popular choices include:

• Visual Studio Code: Free, versatile, and supports extensions.
• Replit: Browser-based, great for quick coding without setup.

3. Explore AI Coding Tools

Now, let’s look at some AI coding tools that will assist you in writing your first 100 lines of code:

| Tool Name | Pricing | Best For | Limitations | Our Take | |--------------------|----------------------------|----------------------------------------|---------------------------------------|------------------------------------------| | GitHub Copilot | $10/mo | Autocompleting code | Not always accurate | We use this for quick code suggestions. | | OpenAI Codex | $20/mo | Generating code snippets | Limited to certain languages | Great for generating boilerplate code. | | Tabnine | Free tier + $12/mo pro | Autocomplete suggestions | May struggle with complex logic | We find it useful for common patterns. | | Codeium | Free | Free AI code suggestions | Fewer integrations | Good for quick tests and prototypes. | | Replit Ghostwriter | $10/mo | Collaborative coding | Less versatile than full IDEs | Useful for pair programming scenarios. | | Sourcery | Free tier + $15/mo pro | Refactoring and improving code quality | Limited language support | We use this to clean up our code. | | Polycoder | Free | Generating code across multiple languages | Slower response time | A fun tool for experimenting with languages. | | Ponicode | $15/mo | Unit test generation | Focused only on testing | Good for ensuring code reliability. | | CodeGPT | $19/mo | Conversational coding assistance | Not always contextual | We find it helpful for debugging. | | AI Dungeon | Free | Interactive coding storytelling | Not a traditional coding tool | A fun way to learn concepts interactively. |

4. Start Coding with AI Assistance

Now that you have your tools, it’s time to start coding. Here’s a simple workflow:

1. Open your IDE and create a new file (e.g., hello_world.py).
2. Use GitHub Copilot to write a simple "Hello, World!" program. Type print("Hello, World!") and see how Copilot suggests the rest.
3. Generate additional code snippets using OpenAI Codex based on your project idea. For instance, if you want to create a simple calculator, ask Codex: “Generate a basic calculator in Python.”
4. Refactor your code with Sourcery to ensure it's clean and efficient.

5. Troubleshooting Common Issues

• Error Messages: If your code isn’t running, check for syntax errors. AI tools can sometimes miss these.
• Logic Errors: AI may generate correct syntax but incorrect logic. Test your code thoroughly.
• Integration Issues: Some AI tools may not work seamlessly with your IDE. Check for plugin compatibility.

6. What’s Next?

After writing your first 100 lines of code, consider exploring more advanced topics, such as:

• Object-oriented programming
• Web development frameworks (like Flask or React)
• Collaborating on open-source projects

Conclusion: Start Here

If you're ready to take the plunge into coding, start with GitHub Copilot for autocomplete suggestions and OpenAI Codex for generating snippets. These tools will guide you through your first 100 lines effectively. Remember, the key is to practice, experiment, and not be afraid of making mistakes.
