Using lambda expression to connect slots in pyqt

by

I am trying to connect slots with lambda functions, but it’s not working the way I expect. In the code below, I succeed in connecting the first two buttons correctly.

I’ve been staring at my screen for a half hour, but I can’t figure out how my code is different.

Since we’re dealing with an existing project, it means you’ll probably need to move some stuff around.
