Flask

How do you "clear" only specific Flask session variables?

In Flask, data stored in the session object can be deleted by popping a specific element from the object.

👇

from flask import session

@app.route('/delete_email')
def delete_email():
    # Clear the email stored in the session object
    session.pop('email', default=None)
    return '<h1>Session deleted!</h1>'
