reading one byte from stdin

[Mark McDuff]

I'm trying to read one byte from stdin, without the newline.

If I try something like:

>>import os, sys
>>os.read(sys.s tdin.fileno(),1 )

I can input a character, but then I have to press enter, which leaves
a newline character in the stdin buffer and requires two keypresses.
Is there any way to read only one keypress in a simple manner (i.e. no
curses)?

Depending on your OS, yes. Under *nix, you need to set the terminal to
RAW-mode.

This recipe claims to be OS-agnostinc:
