If I understand you properly, what you're trying to reinvent is a dict. For each row, use the name (which is data, too, right?) as key and the tuple oe whatever structure you like as value. thing[name] = tuple An alternative, if you really want the names to be real var names, is to put all of that into an object as attributes, using the builtin func setattr: setattr(thing, name, tuple) > Is it possible to change the name through modification of self attribute > (wait is self an attribute?) Don't understand why you want a class here. > Are cats sleeping with dogs here or what? ???
