Study Notes

The Raise Statement

The raise statement is utilized to throw exceptions in Python.
Syntax: raise exception-name[(optional argument)]
The optional argument is typically a string that provides a message when the exception occurs, e.g., "OOPS: An Exception has occurred."

Exception Types

Exceptions can be built-in (like IndexError) or user-defined.
In an example using raise, the IndexError is triggered when the variable length exceeds the list named 'numbers'.

Exception Handling

When an exception is raised with raise, any code following it does not execute.
Example: In the context where an IndexError is raised, the message “NO EXECUTION” will not appear due to the abortive nature of the exception.
