python文本处理json备忘

• json 中文编码出错，比如{"sc": "\u9644\u67d1\u4e52"}

      ensure_ascii = False 加上这个就好了，这个是看的别人的博客上的，感谢

with open('demo.json', 'a', encoding = 'utf-8') as f:
    json.dump(data, f, ensure_ascii = False)

• 以一种易读的格式写入json文件

data = {'name': '小敏', 'age': 20}
 
data_neat = json.dumps(data, indent = 4, ensure_ascii = False)
 
# {
#    "name": "小敏",
#    "age": 20
# }
 
with open('demo.json', 'a', encoding = 'utf-8') as f:
    print(data_neat, file = f)

• json文件或txt文件里的每一行是一个json格式如何读取：
