Working with Sessions in Flask

In Flask, you can store information specific to a user for the duration of a session using the session object.

Saving data for use throughout a session allows the Flask app to keep data persistent over multiple requests.


from flask import request, session

@app.route('/set_email', methods=['GET', 'POST'])
def set_email():
    if request.method == 'POST':
        # Save the form data to the session object
        session['email'] = request.form['email_address']
        return redirect(url_for('get_email'))

    return """
        <form method="post">
            <label for="email">Enter your email address:</label>
            <input type="email" id="email" name="email_address" required />
            <button type="submit">Submit</button
