Почему индексерра происходит, когда я пытаюсь использовать переменную, которая итерации для доступа к данным в массиве и ⇐ Python

[Anonymous]

Я пытаюсь создать программу, которая обрабатывает скриншот в уменьшенное красное изображение только с тремя цветами. Я ожидал получить изображение, однако, я выполнил эту ошибку.for x in range(29):
for y in range(112):
if x and y == 0:
continue
duplicate = False
for z in range(colourFrequency.shape[0]):
if colourFrequency[z][2] = colourFrequency[z][3]:
duplicate = True
colourFrequency[z][1] += 1
break
if duplicate == False:
colourFrequency = np.append(colourFrequency, [image[x][y][2], 1, image[x][y][2], image[x][y][2]])
< /code>
Специально, эта строка. < /p>
if colourFrequency[z][2] = colourFrequency[z][3]:

Я уже искал Stackoverflow и нашел кого -то, у кого была похожая ошибка (как исправить индексерр: недопустимый индекс к скалярной переменной), однако я не смог реализовать предложения, найденные на этой странице, не нарушая код. /> Вот полный сценарий на всякий случай. Строки с 4 по 15 были проверены и работают правильно, однако я не смог проверить остальные, поэтому, вероятно, все еще есть некоторые проблемы. < /P>
