如何在python中将json格式的字符串转换为普通字符串格式

import json

json_str = '{"name": "John", "age": 30, "city": "New York"}'
data = json.loads(json_str)

name = data['name']
age = data['age']
city = data['city']

import json

json_str = '{"name": "John", "age": 30, "city": "New York"}'
data = json.loads(json_str)

name = data['name']
age = data['age']
city = data['city']

print(name)  # 输出：John
print(age)   # 输出：30
print(city)  # 输出：New York
