What's the difference between the RP membership and training.realpython.com?
Update (January 2020): training.realpython.com and training.dbader.org have been shut down and all books, courses, and other products have been migrated to the realpython.com learning platform. More info here: https://realpython.com/news/store-migration/
--- Old info below ---
Previously there was only training.realpython.com where you could access your books and training courses you bought from the Real Python online store.
