[ericBlack1]

Description:
When running the provided Flask application, accessing the root URL http://127.0.0.1:5000/ returns a 404 Not Found error. However, the /home route works as expected.

Steps to Reproduce:

1. Run the Flask application using the provided code snippet.
2. Open a web browser and navigate to http://127.0.0.1:5000/.
3. Observe the 404 Not Found error.
4. Navigate to http://127.0.0.1:5000/home, which works as intended.

Expected Behavior:
The root URL / should display content or redirect to /home.

Actual Behavior:
The root URL / returns a 404 Not Found error.

Code Snippet:

from flask import Flask

app = Flask(__name__)

@app.route('/home')
def home():
    return "Welcome to your first Flask application!"

if __name__ == '__main__':
    app.run(debug=True)

Development Environment:

• OS: Ubuntu 24.04.
• Python Version: 3.12.3
• Flask Version: 3.0.3

Suggested Fix:
Add a route for / to handle root URL requests. For example:

@app.route('/')
def index():
    return "Welcome to the root URL!"
