more info about the pattern you use with re

you´re so right ! did not pay attention in this context...

Nice one!

the first step is to add attribute that creating a tuple that (split the elements into every page)
hidding in this idea , the list slice is important.
list1 = [1,2,3,4,5]
list1[2:10] wondnt cause erro this is the key for the last page filling

very simplie solution

In my experience paginators are used requesting all the information up front is expensive on resources. In situations where we have a lot of data in the collection could constructing pages like this cause problems?

I think it is best solution to create self._pages!

Why do you declare ROMAN_NUMERALS and other consts out of class RomanNumerals?

really good idea, simple, and very clear code !
