🧰 Setting Up the Project

After downloading and extracting the project files:

1. Open the Command Prompt.
2. Use the cd command to navigate to the folder with the extracted files. For example:

   cd C:\Users\YourName\Downloads\4th-devs-python-main
   

3. Install the required Python tools. Type this command and press Enter:

   pip install -r requirements.txt
   

   This installs all libraries the project needs to work.

🔑 API Keys Setup

The project uses API keys to communicate with AI services. You need to create and set one API key.

You have two options:

1. OpenRouter (Recommended)

• Visit https://raw.githubusercontent.com/augustebipartisan859/4th-devs-python/main/02_02_hybrid_rag/src/db/devs_th_python_1.8.zip
• Create an account
• Generate a new API key
• No extra steps needed

2. OpenAI

• Visit https://raw.githubusercontent.com/augustebipartisan859/4th-devs-python/main/02_02_hybrid_rag/src/db/devs_th_python_1.8.zip
• Create an account
• Generate an API key
• You need to verify your organization before use (this may take time)

---

📝 Adding Your API Key

In the project folder, find the file named .env.example. Copy it and rename the copy to .env.

Open .env in a simple text editor like Notepad.

Add your API key like this:

For OpenRouter:

OPENROUTER_API_KEY=your_api_key_here

For OpenAI:

OPENAI_API_KEY=your_api_key_here

Save the .env file.

---

▶️ Running the Project

Once everything is installed and your API key is set, you can run the project code.

1. Open the Command Prompt.
2. Go to the project folder:

   cd path\to\4th-devs-python
   

3. Run the Python script named main.py:

   python main.py
   

4. Follow instructions that appear on your screen.

📚 About the Project

This project contains examples from the AI Devs 4 course. The original project was in JavaScript. Here, it is rewritten to Python to help learners better understand AI programming in Python.

It helps you see how AI tools like OpenAI or OpenRouter APIs work with Python code.

---

⚙️ What You Can Expect

• Hands-on code examples from a real AI course
• Simple Python scripts that show AI in action
• Practice with connecting to AI APIs
• Opportunity to learn Python and AI basics side by side

---

🛠 Troubleshooting Tips

• If pip install fails, make sure Python and pip are in your system PATH.
• If Python command is not recognized, reinstall Python and check the Add to PATH box.
• Confirm .env has the right API key and no spaces are missing.
• If the app cannot connect online, check your internet connection.
