The code was suppose to test if the locations has an "X" as far as I know there is no syntax error. the program keeps asking me if I added the elif. some help is greatly appreciated.
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) - 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: 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" else: print "You missed my battleship!" board[guess_row][guess_col]="X" print_board(board)
