If you need a global variable, use pymol.stored:

from pymol import stored
stored.bk_toggles_W = 0
def bk_toggles_W ():
      "Hides W molecules."
      if stored.bk_toggles_W:
          cmd.hide("all")
          cmd.show("spheres", "not (resn W)")
          stored.bk_toggles_W = 0
      else:
          cmd.show("spheres", "resn W")
          stored.bk_toggles_W = 1

Cheers,
   Thomas
