To be honest, you can define text as "A stream of bytes that are split
up in lines separated by a linefeed", and do some basic text
processing like that. Just very *basic*, but still. Replacing
characters. Extracting certain lines etc.

This is harder in Python 3, as bytes does not have all the
functionality strings has, like formatting. This can probably be fixed
in Python 3.5, if the relevant PEP gets finished.

For the battery analogy, that's like saying:

"I want a battery."

"What kind?"

"It doesn't matter, as long as it's over 5V."
