在Python中将一个Json对象数组拆分为多个数组[重复]

Question

我有一个包含多个 json 对象的数组，我想根据 json 对象的数量将它们分成多个数组。以每个 Array 包含的对象不超过 10 个为例。

[{object-1}, {object-2},....,{object-n}]
Array-1 = [{object-1}, ....,{object-10}]
Array-2 = [{object-11}, ....,{object-21}]
Array-3 = [{object-22}, {object-22}]

查看实际数据，请注意下面的 EventsSelectors 数组。我正在寻找的是提取 EventSelectors 中的所有对象并将它们分解为多个 EventsSelector 数组以供以后处理。最大记录数不应超过 20 条记录。

{
    "EventSelectors": [
        {
            "IncludeManagementEvents": true,
            "DataResources": [],
            "ReadWriteType": "All"
        },
        {
            "IncludeManagementEvents": true,
            "DataResources": [],
            "ReadWriteType": "All"
        },
        {
            "IncludeManagementEvents": true,
            "DataResources": [],
            "ReadWriteType": "All"
        }

    ],
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName"
}

谢谢

见下文

def slicer(lst, n):
    for i in range(0, len(lst), n):
        yield lst[i:i + n]


N = 3
data = [{6}, {7}, {8}, {8}, {1}, {2}, {5}, {77}, {88}, {654}]
sliced = {idx: data for idx, data in enumerate(slicer(data, N))}
print(sliced)

输出

{0: [{6}, {7}, {8}], 1: [{8}, {1}, {2}], 2: [{5}, {77}, {88}], 3: [{654}]}
