如何刪除字典外大括號或將沒有大括號的它附加到列表中？

Question

data = [

]
for x in range(0, len(directory_files)):
    # print(directory_files[x])
    # print(os.stat('Data\\' + directory_files[x]).st_size)
    img = ("Data\\" + directory_files[x])
    img_with_no_tag = directory_files[x]
    size_of_img = str(os.stat('Data\\' + directory_files[x]).st_size)
    img_capsulated = cv2.imread(img, cv2.IMREAD_GRAYSCALE)
    img_capsulated_rgb = cv2.imread(img, cv2.IMREAD_COLOR)
    parent_tag = img_with_no_tag + size_of_img
    contourIndexNo = 0
    listTest = {
        img_with_no_tag + size_of_img: {
            'filename': img_with_no_tag,
            'size': size_of_img,
            'regions': [
            ],
            'file_attributes': {
                'caption': '',
                'public_domain': 'no',
                'image_url': ''
            }
        }
    }
    # print(*listTest, sep="{}")
    data.append(listTest)

這就是我執行代碼的方式。 輸出如下所示：

[

    "138_mask.png4776": {
        "filename": "138_mask.png",
        "size": "4776",

}

這意味着，在將字典值附加到列表中時，我想將它們放入，因為它們不是單獨的對象，或者在將它們寫入 json 文件時是否有其他方法？

我嘗試對 .replace 或 remove 等 json 文件寫入提示進行功能操作，但這沒有用。

Answer 1

您顯示的所需輸出是一個字典，因此只需創建一個字典而不是列表。 這本字典的鍵是你的圖像名稱，例如"138_mask.png4776"

data = {}

然后稍后在您的代碼中將條目添加到字典中：

data[img_with_no_tag + size_of_img] = {
    'filename': img_with_no_tag,
    'size': size_of_img,
    'regions': [],
    'file_attributes': {
        'caption': '',
        'public_domain': 'no',
        'image_url': ''
    }
}

最后，如果你想把這本字典放在一個列表中，你總是可以這樣做：

data = [data]
