I am 100% sure that those who read/use these sources are all capable of coding, Python for specific.
Since nowaday a homepage is less visited even though it is in your favorites, I suggest packing it up as a python package.
Followers could simply import the package to filter/display the dataframe for his own use, other than visiting a homepage.
The codes will be more or less like :
import ccfddl
ddl = ccfddl.get_latest(category=['AI','DB'], begin ='2023-01-26' , level = ['A','B']) # a pandas dataframe
ddl # do whatever you like
In this way, ccfddl will stick to everyone's computer, and every day use of course.
