First, Python support for JSONStarting with python2.6, JSON support has been added to the Python standard library, and it is only necessary to manipulate the JSON import json .Second, the Python object is converted into a
Recently, a third-party called API has been developed for a self-developed software platform. If the returned result set is in JSON format, it is easier to develop it in other languages, I found a lot of information on the Internet and didn't find it very suitable. Finally, I decided to change my mind to write a general one based on the information on the Internet.
The main application scenario of this method is to

When the data structure is simple enough for a two-dimensional table to describe the format,
The comma interval represents the column, \ r \ n represents the row, and the first row is the corresponding property name.
Like

2, "title", "Http://ss.ss.com/ss"
3, "title", "Http://ss.ss.com/ss"
