 Well, the anonymous visitor _is_ accessing "login_py" actually.
(Zope does not check permissions on function call, but on attribute
access.)

 Thus Your idea does not work that way. 
Instead You could check directly, if the user is anonymous, by
inspecting 
  "_.SecurityGetUser().getUserName=='Anonymous User'"
or the like (sorry, if forgot the proper incantation ...)
