具有字符串日期值的列仅为python中的日期类型而不是datetime。或者如何在转换后删除时间戳

Question

Datatype of two objects

image

尝试了以下代码但是出现错误此错误＆＃34; AttributeError：type object＆＃39; datetime.datetime＆＃39;没有属性＆＃39; datetime＆＃39;＆＃34;

Map<String, Object> root = (Map) jsonObject;
Map<String, Object> context = (Map) root.get("@context");
Map<String, Object> image = (Map) root.get("image");
String imageId = (String) image.get("@id");

导入的库： 导入日期时间 从datetime import datetime，timedelta

df_patients['date_of_diagnosis_new'] = pd.to_datetime(df_patients['date_of_diagnosis'])
