python如何将json转成字符串

import json

data = [{

    "name": "Tom",

    "gender": "male"

}, {

    "name": "杰克",

    "gender": "男"  

}]

#将json格式转为字符串

print(type(data))

str = json.dumps(data, indent=2) #indent=2按照缩进格式

print(type(str))

print(str)

#保存到json格式文件

with open('data.json', 'w', encoding='utf-8') as file:

    file.write(json.dumps(data, indent=2, ensure_ascii=False)) #ensure_ascii=False可以消除json包含中文的乱码问题
