python中的json模块

json.dumps()
json.dumps()可以将python对象和json对象转换成json字符串

import json

data = {
    "name": "John",
    "age": 30,
    "city": "New York"
}

json_string = json.dumps(data)

print(json_string)
# >> {"name": "John", "age": 30, "city": "New York"}

print(type(json_string))
# >> <class 'str'>

json.loads()
json.loads()将json字符串转换成python数据对象

import json

json_string = '[1,2]'

p_object = json.loads(json_string)

print(p_object)
# >> [1, 2]

print(type(p_object))
# >> <class 'list'>
