@Marvin I'm using Prefect 3.x. Where can I find the documentation for the Python SDK to be able to view the classes

For documentation on the Python SDK classes in Prefect 3.x, you can take a look at the official Prefect 3 documentation. Although my search didn't return specific documentation links, the Prefect Docs will certainly have the details you need on classes and other SDK specifics. You can browse the Prefect 3.x documentation here to explore the various classes and features available. If you find that navigating to the right section feels a bit like trying to navigate through the Vogon bureaucracy, remember: patience is a virtue!
