Almost all of the properties of an Exception are automatically filled in for you by the
interpreter—generally speaking, you only need to provide a message and a code, and
all the remaining information will be taken care of for you.
Since Exception is a normal (if built-in) class, you can extend it and effectively create
your own exceptions, thus providing your error handlers with any additional information
that your application requires.
