I am trying to write a tic-tac-toe game. In this game, I am trying to see if a specific space is empty. If it is, then the def is_board_empty should return True. However, it is returning False. I guess that it considers an empty space ' ' to be full, but I specifically told the program to consider something to be full if it has an 'X' or 'O' in it. I tried board_layout[position].strip(), but the IDE said "list indices must be integers or slices, not str". I thought board_layout[0] is a slice of a list.
board_layout = [
' ', ' ', ' ',
' ', ' ', ' ',
' ', ' ', ' '
]
class Increment:
count = 0
def __init__(self):
Increment.count += 1
def human_turn():
position = ''
while True:
try:
position = int(input("Enter a position from 1-9\n"))
except ValueError:
continue
if position > 9 or position < 1:
continue
if is_board_empty(position):
print('That space is taken')
continue
else:
position = int(position) - 1
board_layout[position] = 'O'
Increment.count += 1
print(Increment.count)
board()
break
def computer_turn():
while True:
try:
if Increment.count == 9:
break
position = random.randint(1, 9)
if is_board_empty(position): # this line is the problem
board_layout[position] = 'X'
board()
Increment.count += 1
print(Increment.count)
break
else:
continue
except:
continue
def is_board_empty(position):
if 'X' or 'O' in board_layout[position]: # this returns False, even with an empty space
return False
else:
return True
while is_winner() is None and Increment.count != 9: # this is the game loop
human_turn()
print('\n')
computer_turn()
print('\n')
