Armour is not working?

[Piethon]

Then the leather chest plate is never on.

In the event section I have this:

#event stuff
#...
if event.key == pg.K_SPACE:
    if self.player.leather_chest_plate == True:
                        self.show_armour_on_screen = True
                        self.player.leather_chest_plate_on = True
                        if self.player.leather_chest_plate_on == True:
                            self.player.leather_chest_plate_on = False

self.player.leather_chest_plate is always true. My armour is getting displayed on the screen, when I press space.
EDIT: It is not that much extended, that happened when posting.
