Given that the behavior of hasattr is clearly defined in Lib Manual 2.1 as equivalent to

def hasattr(obj, name): try: getattr(obj, name) return True except: return False

I am not sure what could be confusing about it. It is a simple getattr wrapper converting 'got something' to True and 'did not get anything' (raised an exception instead) to False. Users should know this so they don't wastefully write 'if hasattr(o,n): x = getattr(o,n)'
