But do you understand *why* you got the error and what it was telling 
you?

Pyton's error message told you exactly what you had done wrong
although you may not have quite understood it. But do you now see
what the error message was telling you when it said:

--
  File "C:\Python26\TicTacToeD.py", line 150, in main
DisplayBoard(board)
  File "C:\Python26\TicTacToeD.py", line 68, in DisplayBoard
print "\n\t", board[1], "|", board[2], "|", board[3]
TypeError: 'function' object is unsubscriptable

Can you understand it clearly enough that when a similar error
comes up in future you will know what to look for and where?

so you have this

"""Create new game board."""
board = []
for square in range(NUM_SQUARES):
board.append(EMPTY)
return board

for your DisplayBoard I have this;

def new_board():
"""Create new game board."""
board = []
for square in range(NUM_SQUARES):
board.append(EMPTY)
return board

def display_board(board):
"""Display game board on screen."""
print "\n\t", board[0], "|", board[1], "|", board[2]
print "\t", "-"

Re: [Tutor] UNSUBSCRIPTABLE?

Your problem:


def main():
   DisplayInstruct()
   puter, human = Pieces()
   turn = X
   board = NewBoard<<<--This line
   DisplayBoard(board)

if you read my email before, I described this to you :) put brackets on 
the end of NewBoard (so NewBoard() ) and this should work.

No. It means that the object does not have a way to handle []. Many

Re: [Tutor] UNSUBSCRIPTABLE?

Found this book at the local library...

If you're doing the TicTacToe game in chapter 6, then have a look at the 
main function (def main: ) and find the line that says

   board = new_board()

This is likely where your troubles lie...

One thing is certain, Dawson used brackets [] not parens (). When I spoke of

error.
My only alternative now seems to be 'get out the old curry comb' and go
letter by letter, between the monitor and the page. Headache time.



I think Brett's suggestion is the most likely one.  Look for a line
that starts with:

board =

That's probably where your error is.

"subscript" means "a thing in square brackets after a name".  You've

The error means that you're trying to use square brackets after
something that doesn't support them.  It's telling you that 'board' is
a function (as opposed to a list or a dict, for example) and functions
don't support [].

Possibly you're meant to call board:

print "\n\t", board(1), "|", board(2), "|", board(3)

Or, alternatively, you may have assigned to it by mistake somewhere.
