Sessions are very simple in z3.

from zope.app.session.interfaces import ISession

session_data = ISession(request)[your_application_id]

Now access your session data via the dictionary, ie.

shopping_card = session_data['shopping_card']


In a view class it would look like this:

class YourView(object):

     def __init__(self, context, request):
           self.context = context
           self.request = request
	   self.session_data = ISession(request)['your_application_id']


Have a look at zope.app.session.interfaces.ISession and in srichter's
book...
