Generate HTML files in batches, and use the student list (student ID, name) and blog list (name, URL)

Concept

I wanted to write this program for a long time. I knew that I had been in school for more than three weeks before I made up my mind to write it.

Function: automatically generates HTML files through the student list (student ID, name) and blog list (name, URL.

Example file: student list and blog list.

Result file (example): HTML file.
