The solution provided is as following. It doesn’t work properly… When I run the program, I can only input the row number. When I hit “Enter” after inputting the row number, it doesn’t give me the opportunity to input the column number. Anyone knows why?
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) print ship_row print ship_col # Everything from here on should be in your for loop # don't forget to properly indent! 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!" break 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" if turn == 3: print "Game Over" print_board(board) # print turn + 1 here
