I am sorry to jump in but I was having a similar
problem and thought you could help. When I
couldnt get to read a line of input from stdin
with readline, I tried your code segment and I
still have the same problem. It behaves as though
there is no loop and does print anything or read
anything. It just does nothing!
Code:
import sys
while 1:
    import sys
    s = sys.stdin.readline()
    if not s:
        break
    t = s.split()
    print t
