json获取指定Key和Value的问题

Question

path = r'path'
json_list = os.listdir(path)

for json_file in json_list:
    if os.path.splitext(json_file)[-1] == '.json':
        print(json_file)
        with open(os.path.join(path,json_file),'r',encoding='utf-8') as load_f:
            data = json.load(load_f)
            shape = data ['shapes']
            print(shape)

我要获取json指定的内容，下面是运行的结果，我不要最外层的方括号，请问如何实现？
[{'label': '1', 'points': [[100.95238095238096, 173.0], [189.04761904761904, 265.8571428571429]], 'group_id': None, 'shape_type': 'rectangle', 'flags': {}}, {'label': '3', 'points': [[421.19047619047626, 488.4761904761905], [581.9047619047619, 562.2857142857143]], 'group_id': None, 'shape_type': 'circle', 'flags': {}}, {'label': '2', 'points': [[798.5714285714287, 290.8571428571429], [827.1428571428571, 317.04761904761904]], 'group_id': None, 'shape_type': 'circle', 'flags': {}}, {'label': '2', 'points': [[753.3333333333335, 153.95238095238096], [852.1428571428571, 248.0]], 'group_id': None, 'shape_type': 'rectangle', 'flags': {}}, {'label': '2', 'points': [[798.5714285714287, 290.8571428571429], [827.1428571428571, 317.04761904761904]], 'group_id': None, 'shape_type': 'circle', 'flags': {}}]

如何去掉最外层方括号，实现获取的结果如下？

{'label': '1', 'points': [[100.95238095238096, 173.0], [189.04761904761904, 265.8571428571429]], 'group_id': None, 'shape_type': 'rectangle', 'flags': {}}, {'label': '3', 'points': [[421.19047619047626, 488.4761904761905], [581.9047619047619, 562.2857142857143]], 'group_id': None, 'shape_type': 'circle', 'flags': {}}, {'label': '2', 'points': [[798.5714285714287, 290.8571428571429], [827.1428571428571, 317.04761904761904]], 'group_id': None, 'shape_type': 'circle', 'flags': {}}, {'label': '2', 'points': [[753.3333333333335, 153.95238095238096], [852.1428571428571, 248.0]], 'group_id': None, 'shape_type': 'rectangle', 'flags': {}}, {'label': '2', 'points': [[798.5714285714287, 290.8571428571429], [827.1428571428571, 317.04761904761904]], 'group_id': None, 'shape_type': 'circle', 'flags': {}}

json 示例如下：

{
  "version": "3.15.1",
  "flags": {},
  "shapes": [
    {
      "label": "2",
      "points": [
        [
          753.3333333333335,
          153.95238095238096
        ],
        [
          852.1428571428571,
          248.0
        ]
      ],
      "group_id": null,
      "shape_type": "rectangle",
      "flags": {}
    },
    {
      "label": "2",
      "points": [
        [
          753.3333333333335,
          153.95238095238096
        ],
        [
          852.1428571428571,
          248.0
        ]
      ],
      "group_id": null,
      "shape_type": "rectangle",
      "flags": {}
    },
    {
      "label": "2",

        [
          852.1428571428571,
          248.0
        ]
      ],
      "group_id": null,
      "shape_type": "rectangle",
      "flags": {}
    }
  ],
  "imagePath": "a.png",
