Re: Is there a simple way to exit a while loop on keystroke?

Hello,
I am new to python, and have written a simple program to read a port
via telnet. I would like it to run until any key is pressed. Of
course I wouldn't mind requiring a specific keystroke in the future,
but I would think this is simpler for now.

I have used kbhit() and getch() many times in C, but I can't find
anything similar in Python. I am using Linux also, so the msvcrt
code isn't an option. I have tried sys.stdin.read(), but that hangs
UNTIL a key is pressed.
You might want to look at http://docs.python.org/lib/module-curses.html

Another solution is to ask the user to hit CTRL-C
from time import sleep

try:
while 1:
print "BEEP"
sleep(1)
except KeyboardInterrupt:
print "BYE BYE"

HTH,
