IN is what you INput into the python interpeter.
OUT is what the interpreter OUTPUTS.
it's a convention people use in order that they don't have to use the 
 >>> (3 greater-than signs)
to indicate an interpreter input, because the greater-than sign is also 
used by e-mail clients
to indicate the level of quoting in a reply, so >>> will often end up as 
3 vertical bars
in e-mail clients.
