In bash you can also use Ctrl-v followed by special character.
(I used to reset terminal by echo "<Ctrl-v><Esc>c"<Enter>)

Ctrl-v, Enter -> generate 0x0d to command-line
Crtl-v, Ctrl-m -> the same as above
Ctrl-v, Ctrl-j -> generate 0x0a (UNIX \n)

So type:
python -c 'import sys;
then press Ctrl-v followed by Ctrl-j
and type the rest..

In vi it looks like ^@. At CLI it realy does a newline.
I guess, you can no longer call it an one-liner ;-)

I'm not sure whether Ctrl-v is a bash feature. More probably
the tty driver. So, it may be worth tring it on bash-less UNIXes
(that deserve to extinct)
