Sometimes it makes sense to cluster related data together. I tend to do so with a dict, e.g.,
self.group = dict(a=1, b=2, c=3) print self.group[\'a\']
In a language which supports it, I would use a struct. A dictionary would be closest to a structure in Python, at least as far as I see it.
struct
Not to mention, you could add a method to a dictionary anyway if you really wanted to ;)
