With the network :) I've written plenty of programs whose sole
interaction is via sockets (telnet, HTTP, SMTP, whatever), or a
database, or somesuch.

But I've also written my share of interactive programs that use the
console. Plenty of programs don't need the fanciness of a GUI, but
need to prompt the user for stuff. If I write something for my brother
(and only him), I'm inclined to spend less effort on the UI than I
would for something of wide distribution, and console I/O is
approximately zero effort.

BTW, I'm assuming your mention of "input()/raw_input()" is covering
Py3 and Py2, respectively. I have *never* used input() in live Py2
code, and never intend to. It's way too subtle. On those really rare
occasions when you actually want to take something from the user and
immediately eval it, the extra keystrokes for eval(raw_input()) are,
IMO, a small price for the clarity.
