I'm not new to Python, but I didn't realise that sys.stdin could be called
as an iterator, very cool!
However, when I use the following idiom:
for line in sys.stdin:
doSomethingWith(line)
and then type stuff into the program interactively, nothing actually happens
until I hit CTRL-D. I expected that 'doSomethingWith(line)' would execute
after every line I input into the program, just like what used to happen
with:
while True:
line = sys.stdin.readline()
if line == '': break
doSomethingWith(line)
What is the difference?
Thanks for your help!
Tom
