How to create an optional data type in python?

Question

Python

In StandartML, it was possible to organize your own data type, where you could outline the possible options . The

datatype colour = red | blue | green

question is whether it is possible (and whether it is generally advisable) to write something similar in python?
That is, should there be a data type (class) that can have only a few values?

Ideally, I would like to see something like this:
color1 = Color(RED)orcolor1 = Color(s)(Сolors.RED)
