MMoSP004- steem-python Modifying and managing keys through JSON files(通过JSON文件修改和管理密码)

Preface notes(前言备注):

This is the first bilingual post after the combination of Chinese and English. Most people may not be used to it, especially the simple and efficient developers. However, there is no way. In order to avoid being downvoted by some people in the steem community, we can only use bilingual in the same post.
=》这是中英文合并后的双语第一帖,可能大多数人会很不习惯,特别是讲究简单高效的开发者.但,没办法,为了避免因此而被steem社区有的人踩,只能双语同文.

Therefore, we need to talk less nonsense and directly focus on:
=》所以,更要少废话,直接说重点:

1. Save the steem account information and key with JSON file
   =》用json文件保存steem账号信息和密钥
2. steem-python obtains master key from JSON file and modifies the whole set of steem key
   =》steem-python 从json文件中获取master key,修改整套steem密钥.
3. Save the modified set of keys to the JSON file
   =》将修改后的整套密钥,保存到json文件中.
4. In the future, once the key is at risk, you can use this tool to quickly change and save the keys of steem account.
   =》日后,一但密钥出现风险,可以直接用此工具快速更改和保存密码.

Format of JSON file storage(/bots.json):
=>json文件存储的格式(/bots.json):

{
    "nodes": [
        "https://anyx.io",
        "https://steemd.minnowsupportproject.org",
        "https://api.steemit.com"
    ],
    "steems": {
        "myaccount": {
        }
    }
}

Demo for changing the keys and saving it into a JSON file
