If you’re new to Python web development, Flask is one of the easiest frameworks to start with. It’s lightweight, flexible, and perfect for building simple APIs or full web apps. Let’s build a tiny “Hello, World!” app together. 👩‍💻

🛠️ Step 1: Install Flask

Make sure you have Python installed, then run:

pip install flask

🧑‍💻 Step 2: Create `app.py`

from flask import Flask

app = Flask(__name__)

@app.route("/")
def home():
    return "Hello, Flask World!"

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

🚀 Step 3: Run the App

python app.py

Go to http://127.0.0.1:5000/ in your browser — you should see:

Hello, Flask World!

🎉 Congratulations! You’ve just built your first Flask web application. From here, you can add more routes, return HTML templates, or build REST APIs.

💡 Pro tip: Add debug=True while developing to get automatic reloads and detailed error messages.
