It's not an "official" convention I think, but a (single) trailing  
underscore is mainly meant to create something that is close to an  
original definition without shadowing it.
If you subclass an object and bind a thusly underscored method to an event  
to which the original is already bound in the superclass's __init__  
method, they are both getting called on the event unless you do not call  
the superclass's __init__() in your own __init__().
