code: def visit(self, func):
          
  
          base_len = len(self.name)
          return self.visitvalues(lambda o: func(o.name[base_len:].lstrip("/")))
docs: Run ``func`` on each object's path.
  
          Note: If ``func`` returns ``None`` (or doesn't return),
                iteration continues. However, if ``func`` returns
                anything else, it ceases and returns that value.

          --------
          >>> import zarr
          >>> g1 = zarr.group()
          >>> g2 = g1.create_group('foo')
          >>> g3 = g1.create_group('bar')
          >>> g4 = g3.create_group('baz')
          >>> g5 = g3.create_group('quux')
          >>> def print_visitor(name):
          ...     print(name)
          >>> g1.visit(print_visitor)
          bar
          bar/baz
          bar/quux
          foo
          >>> g3.visit(print_visitor)
          baz
          quux
