在Python中将Json对象的数组拆分为多个数组

Question

我有一个具有多个json对象的Array，我想根据json对象的数量将它们分成多个数组。例如，每个数组包含的对象不应超过10个。

[{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。我要找的是提取EventSelectors中的所有对象，并将它们分解成多个EventsSelectors数组以便以后处理。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

Answer 1

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}]}
