I know, I've been scouring over the ASPN recipes and digging through code like there's no tomorrow. But, I don't view it as pointless even though there are existing implementations and solutions out there. First of all, I don't like to stuff a lot of what is obviously library type of code into a project, unless I can reference a library that got that function or class or whatnot. Creates a rather big maintenance nightmare :) So, I would have to stuff that into a library, which is what I did with my "own" function (thank you for helping btw). The recipe on ASPN is probably better than what I got, but... I understand how my solution came about and what makes it tick. Secondly, I've been "programming" Python for, what, about 11 days now or so, so I want to re-implement as much as possibly right now, even to the point where I create a worse solution than an existing one, as long as it works for me, just to be able to learn the nuances of Python, because Python is ... different than what I'm used to. For instance, in C# and .NET you got attributes, but they don't actually do anything on their own, in other words you can't tag a method and have the operation of that method deviate from a similar method without the attribute, unless you pick one of the attributes the compiler knows about, so it's just meta-data that sits silent until some other method goes around to look for it. In Python I've now learned that a function is just an object like everything else and I can wrap a new object around it to modify its behaviour, and I can use the decorator pattern to do it. I'm probably going to be back here in a few days or even hours with another "task" where you can probably cough up dozens of existing source code solutions that I could use. For instance, there's this thing I've heard of called the "wheel"..... :) -- Lasse Vågsæther Karlsen http://usinglvkblog.blogspot.com/ mailto:[EMAIL PROTECTED] PGP KeyID: 0x2A42A1C2 -- http://mail.python.org/mailman/listinfo/python-list
