[英]Sort Nested List value using Dictionary value
我有一个嵌套列表字典。 当列表与标签匹配时，我需要按内部字典对列表（上层列表）进行排序，并按 python 中的值排序。 例如，我想对列表进行排序（“label”==“Name”和内部字典的键“value”的值），这是我的字典，

提前感谢您的帮助。
对于您的问题，我建议采用以下两步解决方案：
import json
with open("test.json") as json_file:
data = json.load(json_file)
labeled_contacts = {}
for contact_props in data:
for contact_prop in contact_props:
if contact_prop["label"] == "Name":
labeled_contacts[contact_prop["value"]] = contact_props
sorted_contacts = [
labeled_contacts[label] for label in sorted(labeled_contacts.keys(), reverse=True)
]
创建一个字典，您可以在其中将列表存储为值，将名称标签存储为键。 要填充字典，请遍历列表列表，然后遍历相应列表中的字典。 找到保存名称标签的字典，并将标签和列表添加到字典中。
然后您可以对字典的键/标签进行排序，然后遍历排序的键并按排序顺序检索您的列表。
如果这 - sorted(all_contact_data_response, key=lambda k: k["value"] and k["label"]==property_name) - 有效，请尝试 [ sorted(all_contact_data_response, key=lambda k: k["value"] and k["label"]==property_name),]但是，我不知道，你在变量 all_contact_data_response 中有什么
我的想法是从内部字典中弹出value键，并将其作为临时变量添加到外部列表中。
# data contains the JSON as a dictionary.
for idx1, item1 in enumerate(data):
value = None
for idx2, item2 in enumerate(item1):
if item2["label"] == "Name":
value = item2["value"]
break
data[idx1].append(value)
现在，一旦我们在外部作用域中拥有该值，我们就可以轻松地使用它来对列表进行排序。
result = sorted(data, key=lambda i: i[-1])
更进一步，您可以删除额外的变量。
for item in result:
item.pop(-1)
好的。 如果我正确理解问题，请尝试此操作
def foo(list_item):
for a in list_item:
if a['label'] == 'Name':
return a['value']
res = sorted(all_contact_data_response, reverse=True, key = lambda list_item: foo(list_item))
访问python中的字典列表并使用值对其进行排序（嵌套字典）

根据另一个嵌套字典的最后一个值，用字典对 python 列表进行排序
