Your page_index method doesn't return for some value. Add some prints and move up the ones you have, figure out why.

collection input: range(1, 25) , items per page: 10
page_index input: 0 , number at index: 1

That's the info of the test your code is failing.

My Python 3.10 code is failing below test, which I can't figure out:

Testing.page_index() method - "page_index returned incorrect value: None should equal 0"

PaginationHelper inputs:
Collection: range(1,25)
Items per page: 10
Page index method input: 24
It's asking for the page index of the number at index 24 from the original list
My code returns index 2, however, am getting above test error message, which I can't figure out, what to fix.

Any help is appreciated!
