Custom error types are user-defined error classes that help in handling specific error scenarios in code.

Can you give me an example of how to create a custom error type?

class MyCustomError(Exception):
    pass

How do I raise this custom error in my code?

You can raise your custom error using the raise statement:

raise MyCustomError('This is a custom error message')

Use custom error types when you need to differentiate between various error conditions in your application for better error handling.
