json转换
json = [{"id":1,"name":1,"age":1},
{"id":1,"name":2,"age":3},
{"id":1,"name":4,"age":4},
{"id":3,"name":3,"age":3},
{"id":3,"name":4,"age":5},
{"id":4,"name":12,"age":10}
]
json2 = [
{
'id': 1, 'list': [
{'name': 1, 'age': 1},
{'name': 2, 'age': 3},
{'name': 4, 'age': 4}
]
}, {
'id': 3, 'list': [
{'name': 3, 'age': 3},
{'name': 4, 'age': 5}
]
}, {
'id': 4, 'list': [
{'name': 12, 'age': 10}]
}

json库
import json
js1 = [
{"id": 1, "name": 1, "age": 1},
{"id": 1, "name": 2, "age": 3},
{"id": 1, "name": 4, "age": 4},
{"id": 3, "name": 3, "age": 3},
{"id": 3, "name": 4, "age": 5},
{"id": 4, "name": 12, "age": 10}
]
stream = json.dumps(js1)
data = json.loads(stream)
print(data)
print(type(data))
str替换法：js1 = [
{"id": 1, "name": 1, "age": 1},
{"id": 1, "name": 2, "age": 3},
{"id": 1, "name": 4, "age": 4},
{"id": 3, "name": 3, "age": 3},
{"id": 3, "name": 4, "age": 5},
{"id": 4, "name": 12, "age": 10}
]
temp = str(js1).replace('\"', '\'')
data = eval(temp)
print(data)
print(type(data)) json = [
{"id": 1, "name": 1, "age": 1},
{"id": 1, "name": 2, "age": 3},
{"id": 1, "name": 4, "age": 4},
{"id": 3, "name": 3, "age": 3},
{"id": 3, "name": 4, "age": 5},
{"id": 4, "name": 12, "age": 10}
]
temp = {}
for i in json:
id_ = i["id"]
name = i["name"]
age = i["age"]
if id_ not in temp:
temp = {'id': id_, 'list': [{'name': name, 'age': age}]}
else:
temp['list'].append({'name': name, 'age': age})
json2 = list(temp.values())
print(json2)
