Python User Define Exception
Creating a User-Defined Exception:
To create a user-defined exception, a new class must be defined that inherits directly or indirectly from the built-in Exception class. Most standard Python exceptions are also derived from this base Exception class.
Raising and Handling User-Defined Exceptions:
User-defined exceptions are raised using the raise keyword and handled using try-except blocks, similar to built-in exceptions.
In this example, InvalidInputError is a user-defined exception that inherits from CustomError, which in turn inherits from Exception. This demonstrates creating a hierarchy of custom exceptions for more organized error handling.
