Why is it doing this

from random import randint

board = []

for x in range(0, 5):
board.append(["O"] * 5)

def print_board(board):
for row in board:
print " ".join(row)

print_board(board)

def random_row(board):
return randint(0, len(board) - 1)

def random_col(board):
return randint(0, len(board[0]) - 1)

ship_row = random_row(board)
ship_col = random_col(board)
guess_row = int(raw_input("Guess Row:"))
guess_col = int(raw_input("Guess Col:"))

print ship_row
print ship_col

if guess_row == ship_row and guess_col == ship_col:
print "Congratulations! You sank my battleship!"
else:
print "You missed my battle ship!"
board[guess_row][guess_col] = "X"
print_board(board)

O O O O O
O O O O O

Guess Row: 5

you might have a 5x5 board, but remember that lists counting at zero, so the indexes are: 0, 1, 2, 3, and 4, that is why you get an index error

you will add code later to handle this, for now, enter something valid

#3

so what do i do to fix it

#4

enter a valid index? You will add code later to handle invalid indexes. Its all in my answer?

#5

ah i get it i had to read it a few times
