python json 列表索引必須是整數或切片，而不是 str 錯誤

Question

我正在制作游戲，我開始處理保存和加載部分，它應該根據 JSON 文件中的值更改一些文本，當我嘗試導入我構建的 giu 的 JSON 文件時，我收到此錯誤

    Traceback (most recent call last):
      File "save_test.py", line 112, in <module>
        object.process()
      File "save_test.py", line 65, in process  
        self.onclickFunction()
      File "save_test.py", line 83, in open_file
        import_text()
      File "save_test.py", line 91, in import_text
        importedText = data_load(['Text']['text'])
    TypeError: list indices must be integers or slices, not str

您將需要一個 JSON 文件，以便您可以導入它然后運行代碼
代碼：

root.withdraw()

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
    text = font.render(importedText, True, green, blue)
    # create a rectangular object for the
    # text surface object
    textRect = text.get_rect()
    textRect.center = (width  // 2, height // 2)
    for object in objects:
        object.process()
    screen.blit(text, textRect)
    pygame.display.flip()
    pygame.display.update()
    fpsClock.tick(fps)

JSON 文件： {"Text": {"text": "import successful"}}

您的代碼將 data_load 作為 function 調用，但它是一個字典。 將您的 import_text function 更改為：

def import_text():
    global importedText
    f = open(importedText)
    data_load = json.load(f)
    importedText = data_load['Text']['text']
