    Flask is a lightweight Python web framework ideal for quickly creating web pages and scalable applications. Below is a step-by-step guide to building a simple Flask web page from scratch.

    1. Set Up the Environment

    Create project folder & virtual environment:

    mkdir my_flask_app
    cd my_flask_app
    python -m venv venv
    source venv/bin/activate # On Windows: venv\Scripts\activate
    Copied!

    Install Flask:

    pip install Flask
    Copied!

    2. Create the Application

    Inside your project folder, create app.py:

    from flask import Flask, render_template

    app = Flask(__name__)

    @app.route("/")
    def home():
    return render_template("index.html")

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

    3. Add Templates

    Flask uses Jinja2 for templating. Create a templates folder and inside it, add index.html:

    <!DOCTYPE html>
    <html>
    <head>
    <title>My Flask Page</title>
    </head>
    <body>
    <h1>Welcome to My Flask Web Page!</h1>
    <p>This page is powered by Python & Flask.</p>
    </body>
    </html>
    Copied!
