``````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[0]) - 1)

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

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"# WHY do we only use  = here, not == here?
print_board(board)``````

my question is
why "board[guess_row][guess_col] = "X" " only has one "="
why is it not "board[guess_row][guess_col] == "X" ?"

Thanks!

What do `=` and `==` do? And what is the purpose of that line? Which one's behaviour matches that intention?
