ERROR MESSAGE
Raising exceptions | |
| We can not only raise exceptions at our own choosing, but we can create Exception classes to manage them. This kind of processing is somewhat beyond the basics, being more appropriate to large applications, especially those using many large modules. These modules may generate their own exception types.
