Validating Enumerated Values
Explore methods for validating enumerated values in Python by using enum classes and set-based validation. Understand how these approaches enhance code readability, support error handling with ValueError exceptions, and maintain robust data validation in object-oriented designs.

The list of valid species isn’t very visible in the previous sections. We’ve essentially buried it inside
the from_dict() method, which may become a maintenance problem. When the source data changes, we need to also update this method, something that can be hard to remember and almost as hard to find. If the list of species becomes long, the lines of code could become hard to read.

Using an explicit enum class with a list ...
