plug-ins. To develop a lightweight paging plug-in, let's start with the most basic requirements of the plug-in. What is the most basic requirement of the paging plug-in? It is nothing more than page display and page switch between pages, therefore, our plug-ins need to focus on this basic requirement, rather than considering other possible requirements for the moment.
Determine the html and css plug-ins
After determining the requirements of the plug-in, the second step is the plug-in UI, that i

$ python --versionPython 3.4.2
2. modify the Python version at the system level.
We can use update-alternatives to change the Python version for the entire system. Log on as a root user. first, list all available python alternative versions:
