Read one key press.

[Gerrit Holl]

Hi,

if I have the following program:

key = raw_input("press a key: ")
if key == 'a':
    print "you pressed 'a'"
elif key == '^['
    print "you pressed escape"

it doesn't work. Well, it works but it itsn't what I'm looking for. I want
ONE key input. Can this me done easyly?

If not, I think there should come a function or a module readkey() with some
constants like ESCAPE, CONTROL, NUMLOCK, ARROW_UP or TAB.

regards,
Gerrit.
