The difference between the four functions Json.dumps () and Json.loads (), Json.dump (), and Json.load () involved in JSON file processing in Python

I. Conceptual understanding

1, Json.dumps () and json.loads () are JSON format processing functions (so to understand, JSON is a string)
(1) the Json.dumps () function is an encoding of a Python data type list in JSON format (so to understand that the json.dumps () function converts a dictionary to a string)
(2) the Json.loads () function converts the JSON format data to a dictionary (as you can understand, the json.loads () function converts a string into a dictionary)

2, Json.dump () and Json.load () are mainly used to read and write JSON file functions

Second, the Code test

1.py

1 ImportJSON2 3 #use of the Json.dumps () function to convert the dictionary to a string4Dict1 = {" Age":" A"}5Json_info =json.dumps (Dict1)6 Print("type of Dict1:"+str (type (DICT1)))7 Print("handled by the Json.dumps () function:")8 Print("type of Json_info:"+str (Type (json_info)))

Run:

2.py

1 ImportJSON2 3 #use of the Json.loads function to convert a string into a dictionary4Json_info ='{"Age": " " "}'5Dict1 =json.loads (json_info)6 Print("type of Json_info:"+str (type (json_info)))7 Print("handled by the Json.dumps () function:")8 Print("type of Dict1:"+str (Type (DICT1)))

Run:

3.py

 1  import   JSON  2  3  #   Json.dump () function, write JSON information into file  4  Json_info =  " {' age ': ' '"}  "  5  file = open (" Span style= "COLOR: #800000" >1.json   ",   w   ", encoding=  " utf-8   " )  6  json.dump (json_info,file) 

Run (1.json file):

4.py

1 Import JSON 2 3 # The use of the Json.load () function will read the JSON information 4 File = open ('1.json','r', encoding='  utf-8')5 info = json.load (file)6  Print(info)
