What are you trying to do exactly? That code is an unreadable mess.

The reason you're getting a blank page is that you only return if 'Filter'
in stuff, since "stuff" is just one of the things you get when you run dir
on class Filters (you have p=Filters and then you do dir(p)), and since
that class has nothing with a "Filter" in its name on its __dict__ that is
never true.

Are you trying to program by coincidence

something?
