dumps,loads与dump,load的区别

可以把dumps和loads对比来看

• json.dumps() 是将python的dict数据类型转换为json字符串
• json.loads() 是将json字符串转换为dict的数据类型

dict = {"name":"xiaoam","age":18}
print(type(dict))
<class 'dict'>
json_data = json.dumps(dict)
print(json_data)
{"name": "xiaoam", "age": 18}
print(type(json_data))
<class 'str'>

dump和loads带有写入和读取的操作

• json.dump(x,y) 其中x是json对象，y是文件对象。是将json对象写入到文件中去
• json.load(y) 是从文件中读取json对象

with open("data.json", "w", encoding="UTF-8") as f:
    s_dump = json.dump(data_obj, f, ensure_ascii=False)
print(s_dump)

with open("data.json", "r", encoding="UTF-8") as f_load:
    r_load = json.load(f_load)
print(r_load)
