真的只会一点点

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

1. import json
   
2. 
   
3. js1 = [
   
4.     {"id": 1, "name": 1, "age": 1},
   
5.     {"id": 1, "name": 2, "age": 3},
   
6.     {"id": 1, "name": 4, "age": 4},
   
7.     {"id": 3, "name": 3, "age": 3},
   
8.     {"id": 3, "name": 4, "age": 5},
   
9.     {"id": 4, "name": 12, "age": 10}
   
10. ]
    
11. 
    
12. stream = json.dumps(js1)
    
13. data = json.loads(stream)
    
14. print(data)
    
15. print(type(data))

str替换法：

1. js1 = [
   
2.     {"id": 1, "name": 1, "age": 1},
   
3.     {"id": 1, "name": 2, "age": 3},
   
4.     {"id": 1, "name": 4, "age": 4},
   
5.     {"id": 3, "name": 3, "age": 3},
   
6.     {"id": 3, "name": 4, "age": 5},
   
7.     {"id": 4, "name": 12, "age": 10}
   
8. ]
   
9. 
   
10. temp = str(js1).replace('"', '\'')
    
11. data = eval(temp)
    
12. print(data)
    
13. print(type(data))
