how to get data from django session

1. Access the session data using the request object:

my_data = request.session['my_data_key']

1. Check if the data exists in the session:

if 'my_data_key' in request.session:
    my_data = request.session['my_data_key']
else:
    my_data = None

1. Use the get() method to access session data with a default value:

my_data = request.session.get('my_data_key', 'default_value')

1. Delete session data when it is no longer needed:

del request.session['my_data_key']
