Python常见问题
我正在构造一个带有键/值对的JSON，如果Name字段为空，Item_2字段为<；0，那么我想删除Name字段。在
我正在使用多达10个嵌套字典，但只有2-10个或1-9个[索引]字典才能满足此条件。在
^ {CD4>}是我的结果列表，它被转入JSON格式，当我打印^ {CD5>}时，只有值打印，而且我看不到空字符串，但是当LREST被丢弃到JSON中时，我看到空白字符串。在
10个字典中的每个字典中的变量可能是空的，也可能不是空的，但是我发送这个JSON的服务器要么需要一个Name字段，要么什么都不需要，而且Name字段对于每个字典都是唯一的。在
这是我的密码
dL311 = dict()
d = dict()
d.setdefault("DriverFirstName",last_edited_user )
d.setdefault("DriverLastName","Aguilar" )
d.setdefault("LastUpdatedBy", "SANSTAR1")
d.setdefault("DACType", dar_item_1)
d.setdefault("Type", "Dead Animal Removal")
d.setdefault("Name", dar_uid_1 )
d.setdefault("DACItemCount", dar_qyt_1)
l311.append(d)

dL311.setdefault("DeadAnimalRemoval", l311)
dResult.setdefault("ListOfLa311DeadAnimalRemoval",dL311)
lResults.append({"MetaData": {}, "SRData": dResult})
作为JSON转储的lResults的结果，我想删除我想要构造一个条件的所有键，该条件声明：
^{pr2}$名称字段为空的lResults的JSON
