This is my code:
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 guess_row = int(raw_input("Guess Row: ")) guess_col = int(raw_input("Guess 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" board[guess_row][guess_col] = "X" print print_board(board)
When I run it it works fine, but prints “None” at the last line, below the “board”. Is it normal (I don’t beleive) and if not, what is wrong?
