Shows the above error in spite of the input being in the range.
I expect the code to work perfectly.
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(1, len(board)) def random_col(board): return randint(1, len(board)) 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 # Write your code below! if guess_row==ship_row and guess_col==ship_col: print "congratulations! You sank my battleship!" else: print "You missed my battleship!" guess_row="x" guess_col="x" print_board(board)
