Hot fix needed - python - battleship - lists 1 - 5

Hey Fellow programmer:
I just need to know how to change my options for battlship. So, I am allowed to pick a number from between 0 - 4 (which equates to 1 - 5 on the grid). I just need to to tell me where I need to put in a patch to where I can input the characters 1 - 5 into the running program and have the corresponding spaces in the program run as well.

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)


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)
print ship_row
print ship_col

for turn in range(4):
print “Turn”, turn + 1
guess_row = int(raw_input("Guess Row: "))
guess_col = int(raw_input("Guess Col: "))

if guess_row == ship_row and guess_col == ship_col:
print “Congratulations! You sank my battleship!”

if guess_row not in range(5) or
guess_col not in range(5):
print “Oops, that’s not even in the ocean.”
elif board[guess_row][guess_col] == “X”:
print( “You guessed that one already.” )
print “You missed my battleship!”
board[guess_row][guess_col] = “X”
if (turn == 3):
print “Game Over”

On those two lines, add -1 to the very end.
