python读取json文件并转换成list存为json，解决存取json中文乱码问题

import json
b=[]
json_file_path = 'newtrain.json'
with open ('train.json',encoding='utf-8') as json_file:
    for line in json_file.readlines():
        dict=json.loads(line)
        b.append(dict)
with open(json_file_path,'w',encoding='utf-8') as file_obj:
    json.dump(b,file_obj,ensure_ascii=False)

其中encoding=‘utf-8’以及ensure_ascii=False都是为了防止中文文件转存乱码的问题
