So I'm doing this exercise, and in theory it should work, and by all accounts it seems the exact code I use works for other people. The code is:
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:")) - 1 guess_col = int(raw_input("Guess Col:")) - 1 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!' board[guess_row][guess_col] = 'X' print board
I'm getting this error message:
Traceback (most recent call last):
File "python", line 33, in
TypeError: 'str' object does not support item assignment
I don't know, but shouldn't it be able to replace it? Line 33 is board[guess_row][guess_col] = 'X'
