Try with this:

class Wrapper2:
   def __init__(self, *args):
        self.handle = CAPI.init(*args)

   def foo(self):
        CAPI.foo(self.handle)

   def restart(self):
        self.handle = CAPI.restart(self.handle)

   def close(self):
        CAPI.close(self.handle)
        self.handle = None

   def __del__(self):
         if self.handle is not None:
                self.close()
