Difference json.dumps () and json.loads () of

First, the difference between the two

json.dumps () is used to convert a string dictionary format

son.loads () is used to convert the string dictionary format

JSON Import 

diction = { 
    "name": "AA", 
    "phonenumber": 13,305,958,697,865, 
    "Grade": "3class"} 

Print (diction) # original file format dictionary 
d1 = json.dumps (diction) # dictionary to convert string 
Print (D1) 
D2 = json.loads (D1) to convert a string dictionary # 
Print (D2) 
Print ( 'D', type (diction)) 
Print ( 'D1', type (D1)) 
Print ( ' d2 ', type (d2))

　　Output:

{'phonenumber': 13305958697865, 'grade': '3class', 'name': 'aa'}
{"phonenumber": 13305958697865, "grade": "3class", "name": "aa"}
{'phonenumber': 13305958697865, 'grade': '3class', 'name': 'aa'}
d <class 'dict'>
d1 <class 'str'>
d2 <class 'dict'>

　Second, note

When the type of error will dict json file data is written, you need to first convert the string format type dict rewrite json file. We need to use json.dumps ()

Open with ( 'd3.json', 'W', encoding = 'UTF-. 8') AS F: 
    f.write (json.dumps (diction)) # write the same character string as a dict through json.dumps () Conversion the json file 
    f.close ()

　　View d3.json contents of the file:

{"phonenumber": 13305958697865, "name": "aa", "grade": "3class"}
