Yep. Those who don't need to join us in the third millennium, and the
resources pointed out in this thread are good to help that.

That's not true for Python 2.

I'd phrase that as:

* Text is a sequence of characters. Most inputs to the program,
  including files, sockets, etc., contain a sequence of bytes.

* Always know whether you're dealing with text or with bytes. No object
  can be both.

* In Python 2, ‘str’ is the type for a sequence of bytes. ‘unicode’ is
  the type for text.

* In Python 3, ‘str’ is the type for text. ‘bytes’ is the type for a
  sequence of bytes.
