Do you mean setting stdin in non-blocking mode ? On unix you can do it with 
the fcntl module (you'll find more infos in the libc docs) :

fcntl.fcntl(sys.stdin, fcntl.F_SETFL, os.O_NONBLOCK)

and catch IOErrors with errno = EAGAIN. But I don't know how to do it in a 
portable way, suggestions welcome :)
