我在熊猫系列中有成千上万行这样的json片段 df["json"]

[{
    'IDs': [{
        'lotId': '1',
        'Id': '123456'
    }],
    'date': '2009-04-17',
    'bidsCount': 2,
}, {
    'IDs': [{
        'lotId': '2',
        'Id': '123456'
    }],
    'date': '2009-04-17',
    'bidsCount': 4,
}, {
    'IDs': [{
         'lotId': '3',
         'Id': '123456'
    }],
    'date': '2009-04-17',
    'bidsCount': 8,
}]
