I have been searching everywhere for the correct syntax to use to change permissions on a dtml method from a python script. I know it could be using manage_changePermissions() but exactly how can I call it on any method.

Do not use "manage_changePermissions". This method is designed a action for the corresponding management interface page. In order to use it, you must build the request in the same way as the action submit would do it -- difficult and very error prone. Instead use "manage_permission". It sets the roles/acquire-flag for a single permission (e.g. the "View" permission). You call it directly on the object for which you want to change the permissions, e.g. the "dtml method". -- Dieter
