I wrote the below code

    @contextmanager
    def _ContextManager(op):
        with OpContext():
            with OpContext.current().Enter(op):
                (yield)
    return stack_context.StackContext(partial(_ContextManager, op))

What's a good function header?
 Here's a good function header?
