Tkinter dropdown menu with search/filter

Python 2.7.13 (yes it is old, no I cannot update)

I have a long list of 100 items of which I need the user to choose 1.

I know Tkinter has a drop down menu, however 100 items is a lot, so it would be better if it had some kind of search function, or at least a filter.
You know the one where you just put the first few letters or numbers and it throws your selector right to the closest option. Like when selecting a country on a website.

Thank you for any and all suggestions!
