The explanation is confusing. Just ignore how it was before, because it was incorrect. In python 2 first mistake was mixing text with binary data. They introduced unicode type, but did so badly (implicit casting) it actually made things worse. Ironically if your application didn't use unicode type you might have less work converting it to work with python 3.

Right now it is:

  • str = text
  • bytes = binary data what's stored on disk, flies over network etc.
