Creating Your First Interactive Website with Flask

Let’s create a simple interactive website using Flask. Follow these steps:

Step 1: Create a New Flask Project

First, create a new directory for your project and navigate into it:

mkdir my_flask_app && cd my_flask_app

Create a new Python file named app.py:

touch app.py

Step 2: Write the Basic Code

Open app.py and write the following code:


from flask import Flask, render_template, request

app = Flask(__name__)

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

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

Step 3: Create HTML Template

Create a folder named templates and add a file named index.html:

mkdir templates && touch templates/index.html

Inside index.html, add the following code:





    
    
    Interactive Website


    Welcome to My Interactive Website!

Step 4: Handle User Input

Modify your app.py to handle form submissions:


@app.route('/submit', methods=['POST'])
def submit():
    user_input = request.form['user_input']
    return f"You entered: {user_input}"

Step 5: Run Your Application

Run your Flask application:

python app.py

Visit http://127.0.0.1:5000 in your browser, and you will see your interactive website!
