'function' object has no attribute '__getitem__' - python-2.7

Question

This is my first time coding. I'm doing it as ab elective module. I have to program an ai_player to go from playing randomly to winning and I'm stuck. Any advice would be appreciated. The game is Connect 4. i keep getting "object has no attribute" error.
import random
import time
def board():
for i in range(0, 8, 1):
for j in range(0, 10, 1):
board[i][j] = 0
return board
def move(board, valid_move):
start_time = time.time()
x = 0
while x == 0:
i = range(7, -1, -1)
j = range(0, 10, 1)
first_move = board[i][j]
board[7][4] = 1
if board[i-1][j] == 0: #above
first_move = [i, j]
x = 1
print " valid above"
return j
elif (board[i][j+1] == 0 and (i <= 7 and j <= 9)) or (board[i-1][j+1] == 0 and (i <= 7 and j <= 9)) or (board[i-1][j+1] == 0 and (i <= 7 and j <= 9)): #right
first_move = [i, (j+1)]
x = 1
print " valid right"
return (j+1)
elif board[i][j-1] == 0 or board[i-1][j-1] == 0 or board[i-1][j-1] == 0: #left
first_move = [i, (j-1)]
x = 1
print " valid left"
return (j-1)
else:
r = random.randint(0, 7)
c = random.randint(0, 9)
first_move = [r, c]
x = 1
print " random move"
return c
end_time = time.time() - start_time
print end_time
return first_move

Answer 1

It looks like you're trying to create a multidimensional list called board. This is not how you do that though, what you've actually done is created a function called board, and then you try to index that function, which fails since it's not a list.
To create board, use something like
board = [[0] * 10 for i in range(0, 8)]
