Align tabs from right to left using ttk.Notebook widget

Question

I want to align tabs (panes) inside a ttk.Notebook widget from right to left (the default is from left to right). How might this be done?

Below is my current code:

Answer 1

In Oblivion's line:

s.configure('TNotebook', tabposition='ne')

the 'ne' bit can be:

nw => above (north) and toe the left (west)
ne => above and to the right (east)
en => to the right (east), at the top
es => to the right (east), at the bottom
se => below (south) and to the right (east)
sw => below (south) and to the left (west)
ws => to the left (west) and to the bottom (south)
wn => to the left (west) and at top

'nw' is, I guess, the more common one, but an application may require it otherwise.
