file reading latency is mainly caused by large reading frequency, so reduction
of the frequency of file reading may be way to solved your problem.
u may specify an read bytes count for python file object's read() method, some
large value(like 65536) can be specified due to ur memory usage, and u

If you are looking for a "real" python to C, well in this case
C++ look for the shedskin compiler. It will take a rather
nice subset of Python and generate C++ code from it.
It is still rather experimental but I have been using it.

Greetings! I am trying to make a multiplayer (no AI, 2 person) game of
tic tac toe in Python. So far it has been pretty simple. My only
concern is with the win checking to see if a person has won. At first
it looked like it was working, but now it sometimes assigns a win when
you enter an X or
Thank you. It seems I didn't understand logic statements as much as I
thought I did!
The one remaining question I have deals with this:
if gameboard[cell] not in 'OX':
gameboard[cell] = 'O'
else:
print "This cell is already filled."
turnnumber -= 1
(gameboard[cell]
So is there a way I have to set up the string OX in the beginning? Is
this where it houses the location of the Xs and Os to determine whether
or not a letter is already there?

Nevermind my previous reply: I've been fixing up the code and

209 lines in the previous version! The changes are immense!
The only problem I have is whenever player two goes, it says the cell
is filled. But the code:

The code's indentation was fine - I forgot to declare cell in player
two's section and not just in player one.

obstacle is my tie checker; it doesn't seem to like what I have:
