Conversion of JSON string to Python type (dictionary)

A. JSON into a dictionary:

Product.json file: Converts the contents of the file into a Python dictionary, as follows:

Method one: Use. Loads (), read first and then convert

Import JSON #导入json, note: The JSON string is a string

f = open (' Product.json ', encoding = ' utf-8 ')

res = F.read ()

Product_dic = json.loads (res) #把json串, into Python data type, dictionary

Print (pruduct_dic) #如结果:

Method two: Use. Load (File object), automatically read the file and convert

f = open (' Product.json ', encoding = ' utf-8 ')

Product_dic = Json.load (f) #传一个文件对象, load () is an automatic read and convert file

Print (product_dic) #如结果:

Two. Dictionary converted to JSON string

Method one:. Dumps (dictionary name)

The dictionary is as follows:

FW = open (User_info.json ', ' w ', encoding = ' utf-8 ')
Dic_json = Json.dumps (d,ensure_ascii=false,indent=4)  #字典转化成json, the dictionary is converted into a string. Which, D, dictionary; ensure_ascii=false processing Chinese, remove the words will be garbled, Indent=4,json format indent bytes
Fw.write (Dic_json)
The results are as follows:

Method two:. Dump (dictionary name)

FW = open (User_info.json ', ' w ', encoding = ' utf-8 ')
Dic_json = Json.dump (d,fw,ensure_ascii=false,indent=10)  #直接操作文件, do not write
View the file results as follows:
