Python JSON module dumps loads

The use of JSON data in Python.

Dumps and loads also need to be paired, just like C + + New/delete Malloc/free need to be used in pairs.

Looking at a string like JSON, it's not necessarily a JSON string. Ha ha.

Let's take a look at examples.

1 #Coding=utf-82 3 ImportJSON4 5data = {"name":"Zhang San"," Age": 18,"friend":["Pock","John Doe"]}6 PrintData7 Printjson.dumps (data)8 PrintJson.dumps (data, indent=4)##设置输出格式9 PrintJson.dumps (data, indent=4, Ensure_ascii=false)##非二进制编码Ten  One Print "*"* 50 ADATA_STR = json.dumps (data, indent=4, ensure_ascii=False) -Data_js =json.loads (DATA_STR) - Printdata_js[" Age"]##读取元素 the PrintData_js.get ("Chengshi","BJ")##如果读取不到可以设置默认值

Output:
