Normally: a(T) where T is an object of type/class Test. So your second approach is notionally correct (aside from making a throwaway object that is then discarded). | BTW: | I don't see what the problem is if I ask a question just because I am curious about it. There's nothing wrong with it at all. But often, questions arise from some other circumstances and this one is of such a flavour that if you wanted this code in a real application it would _often_ be the wrong solution to seek, because normally you know how to call something - it is not normally useful to introspect it to decide what to do. So I was wondering what the outer context might be, because there may well have been a better solution to the situation that brought up the specific question. Simple curiosity is sufficient reason, of course. -- Cameron Simpson <c...@zip.com.au> DoD#743 http://www.cskk.ezoshosting.com/cs/ Too young to rest on the weekend, too old to rest during the week. - Mark Randol <ryv...@email.sps.mot.com> -- http://mail.python.org/mailman/listinfo/python-list
