Since you'll get an instance of an item in the list, it will be a 
MyListViewItem (assuming, of course, that that was what you 
instantiated in the first place.)

isinstance(item, MyListViewItem). Usage of isinstance() is frowned by 
Python purists though, and they would probably suggest that your 
different types of item objects all implemented e.g. an itemType() 
method for figuring out what kind of item it is.
