Python中关于json.load()和json.loads(),json.dump()和json.dumps()区别

• json.load()是从文件中读出json格式的字符串;

with open('text.json','r',encoding='utf-8') as f:
    print(json.load(f))

控制台打印结果:

{ "name": "anthony", "sex": "man" }

• json.loads()是将json格式的字符串转为字典类型。

# -*- coding :utf-8 -*-

import json

def test():
    content = '{ "name": "anthony", "sex": "man" }'
    print(type(json.loads(content)),json.loads(content))

if __name__ == '__main__':
    test()

控制台打印结果:

<class 'dict'> {'name': 'anthony', 'sex': 'man'}

Process finished with exit code 0

• json.dumps()是将python中的字典类型转为字符串类型;

dicts = {'name':'anthony','sex':'man'}
print(type(json.dumps(dicts)),json.dumps(dicts))

控制台打印结果:

<class 'str'> {"name": "anthony", "sex": "man"}

• json.dump()函数是将json格式的字符串写到一个文件中。

content = '{ "name": "anthony", "sex": "man" }'
with open('text.json','w',encoding='utf-8') as f:
    json.dump(content,f)

结果:在当前目录下创建text.json文件，其中的内容为:

"{ \"name\": \"anthony\", \"sex\": \"man\" }"
