I don't know why global accessibility is such a problem.

Anyway, in practice I handle such "static" variables as module globals.
If you want a more puristic solution, you could do:

   def _make_f():
       x = 0
       def f():
           nonlocal x
           x += 1
           return x
       return f

   f = _make_f()

   print(f())
   => 1
   print(f())
   => 2
   print(f())
   => 3
