How to use JSON data in Python? (code example)

JSON is a JavaScript object notation. It means a script (executable) file consisting of text in a programming language that can be used to store and transfer data. So how to use JSON data in Python? This article will give you a brief introduction to how to use JSON data in Python. I hope it will be helpful to you.

Python can support json through a built-in package called json; to use this feature, we need to import this json package in the python script.

The following is a simple code example to introduce how to use JSON data in Python.

Example 1:

#导入JSON包
import json 
#键:值 映射
a ={
   "name":"John", 
   "age":31, 
    "Salary":25000
   } 
#通过dumps()函数转换为json
b = json.dumps(a);
#输出
print(b) ;

Output:

Explanation:

Text in JSON is completed by a quoted string that contains the value in the key-value map. It is similar to a dictionary in Python. JSON exposes an API similar to that used by users of the standard library's marshal and pickle modules, and Python natively supports JSON features.

Example 2:

#导入JSON包
import json 

# JSON支持不同的基元类型
print(json.dumps(['Welcome', "to", "GeeksforGeeks"])) 
print(json.dumps(("Welcome", "to", "GeeksforGeeks"))) 
print(json.dumps("Hi")) 
print(json.dumps(123)) 
print(json.dumps(23.572)) 
print(json.dumps(True)) 
print(json.dumps(False)) 
print(json.dumps(None))

Output:

Explanation: JSON supports basic types, such as strings and numbers, as well as nested lists, tuples and objects
