Warning: The below code wasn't tested at all...
-------------------------------
from Queue import Queue, Empty
from sys import stdin
from threading import Thread
# Reading from empty stdin error
class EmptyError(Exception): pass
# Input queue
_queue = Queue()
def produce():
'''Read one char at a time from stdin and place in _queue'''
try:
while 1:
c = stdin.read(1) # Read one char
if not c: # EOF
_queue.put(EOFError, 1)
break
_queue.put(c, 1)
except EOFError, e:
_queue.put(EOFError)
# Start the thread
t = Thread(target=produce)
t.setDaemon(1) # Don't inhibit interperter exit
t.start() # Start thread
def get():
'''Get one item from queue.
Might raise EmptyError if queue is empty or EOFError of end of input
'''
try:
val = _queue.get(0)
if val is EOFError:
raise EOFError
return val
except Empty:
raise EmptyError
def is_empty():
'''Tell if no input is ready'''
return _queue.empty()

HTH.
