Hello All,

I mainly code in Python, and is quite confused with the IO part.
Well I normally do the following for IO:

f = open('filename','r')
a = f.read()
b = a.split('\n')

Now, depending on the problem at hand, I use a for loop / while loop to
look over all cases and solve them accordingly.
I believe this is time consuming (when there is a very big input), and when
I download the solution, they all are written something like this:

(Code taken from the Analysis for Tic-Tac-Toe-Tomek)

numcases = int(sys.stdin.readline())
for casenum in range(1,numcases+1):
   board = []
   for i in range(0,5):
     board.append(sys.stdin.readline().strip())
   print 'Case #' + repr(casenum) + ': ' + solve(board)



Now, when we run this code, we have to manually write down everything - and
then it will solve the problem. Is there a way to do it via command line to
solve everycase in one go?

And, is there any good material on Python IO which touches on stuff like
above?
Thanks.
