db.tbdailydate.aggregate([ {$match:{"activity_no":"3VSWM91OVOZS6LP0Z9YWE11O","create_time":{$gte:new Date("2023-05-01T00:00:00.000Z")}}, {$group:{_id:"$create_time",count:{$sum:"$use_num"}}} ])转成Aggregation类方式

Sure, 以下是将该聚合查询转化为Aggregation类方式的代码：

from datetime import datetime

pipeline = [
    {
        '$match': {
            'activity_no': '3VSWM91OVOZS6LP0Z9YWE11O',
            'create_time': {'$gte': datetime(2023, 5, 1)}
        }
    },
    {
        '$group': {
            '_id': '$create_time',
            'count': {'$sum': '$use_num'}
        }
    }
]

result = db.tbdailydate.aggregate(pipeline)

请注意，需要在代码中导入datetime模块来创建日期对象并将其传递给聚合管道。还需要将`new Date()`转换为Python datetime对象。
