Question

I have a spinbox that needs to have double zeroes, like a clock. No matter what I try, I get only 1. Is it even possible to have a spinbox display double zeroes?

# all give same options: 0 - 15 - 30 - 45
Spinbox(root, from_=00, to=45, increment=15)
Spinbox(root, values=('00', '15', '30', '45'))

Answer 1

Entirely possible!
Use the format= option.

Spinbox(root, from_=00, to=45, increment=15, format="%02.0f")

That should give you what you need. Take a look at the format docs for more information.
