there are not error messages.
I wanna this code can correct non-int type like '[3,4]' or '1,3'. So I add code like below:
if type(guess_row)!='int' or type(guess_col)!='int':
And if I input something like '[3,4]' or '1,3', It print "WHAT?!". but I input correct code like '3', they also print "WHAT?!".
What's the problem?
Replace this line with your 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) guess_row = raw_input("Guess Row:") guess_col = 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: if type(guess_row)!='int' or type(guess_col)!='int': print "WHAT?!" elif 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 print_board(board)
