Because that's the default. Because lots of existing code still uses
classic classes, so you need to learn them anyway. Because you can't use
new-style classes in code intended for 2.1 or earlier; because of the
changes made in 2.3, I don't particularly recommend new-style classes for
2.2. Because even the second edition of _Learning Python_ (targeted at
Python 2.3) doesn't cover new-style classes much, so I'm certainly not
alone in believing that new-style classes are better avoided for newbies.
