Thanks. I'm just trying to see if there is some concise syntax available
without getting into obscurity. As for my purpose Siegmund's suggestion
works quite well.
The few forms you have suggested works. But as they refer to list multiple
times, it need a separate assignment statement like
list = s.split('=',1)
I am think more in the line of string.ljust(). So if we have a
list.ljust(length, filler), we can do something like
name, value = s.split('=',1).ljust(2,'')
I can always break it down into multiple lines. The good thing about list
unpacking is its a really compact and obvious syntax.
