Hi, Some questions about which I am a bit confused. 1. I know there is a difference between mro of classic and new style classes. but I do not get why we need the new mro, the old one is easy to predict and understand?
2. A friend of mine told me that in C++ abstract classes are classes which can not be instatiated. Is she right, do we have them in python, if yes can someone give a simple example? 3. In http://www.alan-g.me.uk/tutor/index.htm , Alan has given an example in "User Defined Exceptions", >>> class BrokenError(Exception): pass Even after reading the section a few times over, I fail to get utility of such a class. Can someone please explain with better example? Alan can you please cleanup that section, maybe make it broader and put the stuff about "SystemExit" elsewhere. Thanks a lot in advance.
