all_presets = Krita.instance().resources('preset')
BRUSH_ONE = "f) Charcoal Rock Soft"
BRUSH_TWO = "b) Basic-5 Size"
currentView = Krita.instance().activeWindow().activeView()
active_brush = currentView.currentBrushPreset().name()
if active_brush == BRUSH_ONE:
new_brush = BRUSH_TWO
else:
new_brush = BRUSH_ONE
currentView.setCurrentBrushPreset(all_presets[new_brush])
