The recipe doesn't get into this to reduce complexity but the various CREATE / DROP phrases would be encoded into DDL() objects as in http://docs.sqlalchemy.org/en/latest/core/ddl.html , or for more structure objects like CreateSP, DropSP etc as DDLElement subclasses associated with compiler hooks as in http://docs.sqlalchemy.org/en/latest/core/compiler.html#dialect-specific-compilation-rules , These objects are then linked into the create_all() sequence using the above described "after_create" event hooks.
A new section could be added to the recipe illustrating this as an additional step to take after all the other concepts are explained. though I'm writing this on my phone at the moment.
