How can I raise user-defined exceptions in python?

Question

Hello,

I have the following code, which consists of a class "Errors" which is meant to have classmethods with user-defined errors.

The code snippet was taken out of a program, however it doesn't rely on the rest of the code.

When I call a class method, which raises a certain error, at the end I get "NameError" - which means that the error from a classmethod I have called does not exist - this is true indeed.

I want to be able to call user-defined exceptions without a "NameError" pop up at the end. How can I do so? And do I need to inherit Exceptions class into my own class?

That's exactly what I wanted:

Used classmethods in here, but someone said to store user defined errors in a package rather than a class
