but again this blocks too.
is there a way to do this, wait for user input but dont block? I could
use a thread that just does the previous code block but i already have
three Thread classes, its just getting too complex with threads!
If your script only needs to be run on Windows -as the subject
suggests- you can use the msvcrt module:
from msvcrt import kbhit,getch
stop = False
while not stop:
print "Hello world!"
if kbhit(): stop = getch()=='q'
kbhit() is used to detect when a keypress is waiting, so the next
getch() will not block.
