It implies that each part with a twofold highlight will be changed to _object._class__variable when attempting to call utilizing an article. The motivation behind this is to caution a client so he doesn't utilize any private class variable or capacity unintentionally without understanding its states.
The utilization of single highlight and the twofold highlight is only a method of name ruining since Python doesn't take people in general, private and secured terms much truly so we need to utilize our naming shows by putting single or twofold highlight to tell the individual software engineers which class they can access or which they can't.
