如何将数字按顺序依次填入json value 中？

Question

有这样一个json，其中3个label全部为“t”，我需要将label依次替换成“1”，“2”，“3” 请问我如何将数字依次更改到label中？

↓原json：

{
  "version": "4.5.10",
  "flags": {},
  "shapes": [
    {
      "label": "t",
      "points": [
        [
          2132.5,
          648.0
        ]
      ],
      "group_id": null,
      "shape_type": "point",
      "flags": {}
    },
    {
      "label": "t",
      "points": [
        [
          2135.0,
          748.0
        ]
      ],
      "group_id": null,
      "shape_type": "point",
      "flags": {}
    },
    {
      "label": "t",
      "points": [
        [
          2130.0,
          850.5
        ]
      ],
      "group_id": null,
      "shape_type": "point",
      "flags": {}
    }
  ],
  "imagePath": "1653041701.jpg",
  "imageData": null,
  "imageHeight": 2160,
  "imageWidth": 3840
}

↓希望替换成的json：

{
  "version": "4.5.10",
  "flags": {},
  "shapes": [
    {
      "label": "1",
      "points": [
        [
          2132.5,
          648.0
        ]
      ],
      "group_id": null,
      "shape_type": "point",
      "flags": {}
    },
    {
      "label": "2",
      "points": [
        [
          2135.0,
          748.0
        ]
      ],
      "group_id": null,
      "shape_type": "point",
      "flags": {}
    },
    {
      "label": "3",
      "points": [
        [
          2130.0,
          850.5
        ]
      ],
      "group_id": null,
      "shape_type": "point",
      "flags": {}
    }
  ],
  "imagePath": "1653041701.jpg",
  "imageData": null,
  "imageHeight": 2160,
  "imageWidth": 3840
}

json_data = {
  "version": "4.5.10",
  "flags": {},
  "shapes": [
    {
      "label": "t",
      "points": [
        [
          2132.5,
          648.0
        ]
      ],
      "group_id": None,
      "shape_type": "point",
      "flags": {}
    },
    {
      "label": "t",
      "points": [
        [
          2135.0,
          748.0
        ]
      ],
      "group_id": None,
      "shape_type": "point",
      "flags": {}
    },
    {
      "label": "t",
      "points": [
        [
          2130.0,
          850.5
        ]
      ],
      "group_id": None,
      "shape_type": "point",
      "flags": {}
    }
  ],
  "imagePath": "1653041701.jpg",
  "imageData": None,
  "imageHeight": 2160,
  "imageWidth": 3840
}

for index, temp in enumerate(json_data['shapes']):
    temp['label'] = index + 1
print(json_data)
