Danny, great reply. I have looked a bit at pyObjC, and it does indeed look cool. I was however hoping to bypass that route altogether and go for the simplicity (I thought) that came with the html/js route. Perhaps a cocoa bundle is the only way to get what I'm after. Thanks, -MH On Mar 25, 2005

Re: [Tutor] Defining functions

Yeah. And they're thinking of removing raw_input() too. I think it's good to have a __builtin__ user input function. Why should we have to import sys everytime we want user input? Almost every program that newbies write uses it, and advanced programmers also if they're using console programs.
