Python 从嵌套字典中删除某些键的优雅方法

我想从以下嵌套字典中删除以下“date”和“last_modified”键。请推荐任何优雅的方法来在Python中动态执行此操作

{
   "total_pages":1,
   "datasets":[
      {
         "dataset_name":"enterpriseqa-landing-zone_census2017",
         "database":"enterpriseqa-landing-zone",
         "table":"census2017",
         "owner":"qadataengineer",
         "zone":"landing",
         "date":"2020-06-09T07:11:25+00:00",
         "location":"s3://enterpriseqa-landing-zone/static/census2017/",
         "count":"5507",
         "classification":"csv",
         "last_modified":"2020-06-09T07:15:49+00:00",
         "type":"Static"
      }
   ]
}

---

如果

d

是问题中的词典，则可以使用此示例删除键：

for dataset in d['datasets']:
    del dataset['date']
    del dataset['last_modified']

生成此词典：

{
    "total_pages": 1,
    "datasets": [
        {
            "dataset_name": "enterpriseqa-landing-zone_census2017",
            "database": "enterpriseqa-landing-zone",
            "table": "census2017",
            "owner": "qadataengineer",
            "zone": "landing",
            "location": "s3://enterpriseqa-landing-zone/static/census2017/",
            "count": "5507",
            "classification": "csv",
            "type": "Static"
        }
    ]
}

如果

d

是问题中的词典，则可以使用此示例删除键：

for dataset in d['datasets']:
    del dataset['date']
    del dataset['last_modified']

生成此词典：

{
    "total_pages": 1,
    "datasets": [
        {
            "dataset_name": "enterpriseqa-landing-zone_census2017",
            "database": "enterpriseqa-landing-zone",
            "table": "census2017",
            "owner": "qadataengineer",
            "zone": "landing",
            "location": "s3://enterpriseqa-landing-zone/static/census2017/",
            "count": "5507",
            "classification": "csv",
            "type": "Static"
        }
    ]
}

您可以这样做：

keys = ["date", "last_modified"]
[[d.pop(key) for key in keys] for d in dictionary["datasets"]]

字典就是你的字典。

你可以这样做：

keys = ["date", "last_modified"]
[[d.pop(key) for key in keys] for d in dictionary["datasets"]]

你的字典在哪里
