How would you lawgic this phrase?

From PT B - Section 1 - Question 06.

None except the most virtuous deserve praise

I know it's part of the 4th group, where you negate the necessary. But I've only seen examples like "none of the Americans are political" and there's no video guide for this one.

How does the "except" affect the translation?

I'm unsure if this is supposed to be...

DP -> MV
MV -> DP

I think I would first think of the sentence as "Only the most virtuous deserve praise" which would then translate to = DP -> MV

I agree with the above comment. If you take a step back, basically what it's saying is that in order to deserve praise, a necessary condition is that you are the most virtuous. If you are not the most virtuous, then the NC fails and you don't deserve praise. So, I would map it out as
DP--->MV.
