Sorry, a bit of a newbie question here. I am just learning Python, and
am going through 'Learning Python' by O'Reilly. I am looking for a way
to open the keyboard/console as unbuffered. Here is their example:
while 1:
next = sys.stdin.read(1)
if not next:
break
<process character 'next'>
I have tried this, but the system input still seems to be buffered.
Not until Enter is pressed does the processing of any of the input
characters occur.
What I would like to be able to do is do a stdin.read(1), and if no
character is available, just go to the top of the loop and try again.
I have looked at the Curses getkey() and getch(), but I don't really
want Curses. Also, I have tried to open the /dev/console and /dev/kbd
as unbuffered, but I get a 'Permission denied' error.
Any help is appreciated.
