flask clear session

To clear a session in Flask, you can follow the steps below:

  1. Import the session object from the flask module. This object represents the user's session.

  2. Use the session.clear() method to remove all the session data. This method clears all the values stored in the session.

  3. Finally, you can redirect the user to a different page or render a template to display the updated session state.

Here is an example code snippet that demonstrates how to clear a session in Flask:

from flask import Flask, session, redirect, render_template

app = Flask(__name__)
app.secret_key = 'your_secret_key'

def clear_session():
    return redirect('/')

if __name__ == '__main__':

In this example, we import the necessary modules and create a Flask app. We set a secret key for the app to securely handle session data.

The /clear_session route is defined, which will be used to clear the session. Inside the route function, we call session.clear() to remove all the session data. Then, we redirect the user to the root page ("/").

Remember to replace 'your_secret_key' with a secure secret key of your choice.

That's it! Following these steps will allow you to clear the session in Flask.
