The image doesn't show up for me. I'm guessing you are referring to a spin button, two buttons that can be used to increment or decrement a value. Is that correct? Tkinter has a Spinbox which is a spin button and an entry combined together.

A ttk.Combobox looks quite like that, probably less the icons.
