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
, theIndexError
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.
