如何删除字典外大括号或将其不带大括号附加到列表中？

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)

这就是我执行代码的方式。输出显示如下：

[

        "size": "4776",

}

这意味着，在将字典值附加到列表中时，我想将它们放在一起，因为它们不是单独的对象，或者在将它们写入 json 文件时是否有其他方法？

我尝试对 json 文件写入提示进行功能操作，例如 .replace 或 remove，但这没有用。

Answer 1

您显示的所需输出是字典，因此只需创建字典而不是列表。这个字典的键是你的图像名称，例如 "138_mask.png4776"

data = {}

然后稍后在您的代码中将条目添加到字典中：

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，如果你想把这本词典放在一个列表中，你总是可以这样做：

data = [data]
