TypeError: 'int' object is not subscriptable board[y][x]

Code:

    board = []
    bWidth = 10
    bHeight = 20
    for h in range(bHeight):
        row = []
        for w in range(bWidth):
            row.append(0)
        board.append(row)
    
    for y in range(bHeight):
            for x in range(bWidth):
                if board[y][x] == 0:

Error:

TypeError: 'int' object is not subscriptable

Answer 1

it appears as though the code is missing something inside the second loop. If i put a generic print statement there, it does get to the end and produces an array of zero's.

board = []
bWidth = 10
bHeight = 20
for h in range(bHeight):
    row = []
    for w in range(bWidth):
        row.append(0)
    board.append(row)

for y in range(bHeight):
        for x in range(bWidth):
            if board[y][x] == 0:
                print('hello', x, y)  # <--- this or pass

board

gives this:
