The console keeps saying list out of range when I put in five for either guess coordinates

it should put an X when the guess is within the rows and coulums

``````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))

def random_col(board):
return randint(0, len(board))

ship_row = random_row(board)
ship_col = random_col(board)
gr = int(raw_input("Guess Row:"))
gc = int(raw_input("Guess Col:"))

print ship_row
print ship_col

if gr == ship_row and gc == ship_col:
print "Congratulations! You sank my battleship!"
else:
if gr == range(5) or gc == range(5):
print "Oops, that's not even in the ocean."
elif board[gr][gc] == 'X':
print "You guessed that one already."
else:
print "You missed my battleship!"
board[gr][gc] = "X"
print_board(board)``````

this:

``if gr == range(5) or gc == range(5):``

won't work, how can a single number equal a list?

use the `in` keyword to check if gr and gc are in range

#3

Thank you, that helped but it keeps saying list index error. It has something to do with the elif function

#4

can i see an updated version of your code?

print "You guessed that one already."
else:

board[gr][gc] = 'X'
print_board(board)``````

you enter 5 as coordinate? that won't work, lists are zero index based so possible values are: 0, 1, 2, 3, 4
