Please have a look at 

https://github.com/ipython-contrib/IPython-notebook-extensions/pull/11

it implements what you asked in no_exec_dunder.js

Put it in `.ipython/profile_default/static/custom/`

then add the following to your custom.js

$([IPython.events]).on('app_initialized.NotebookApp', function(){
      require(['custom/no_exec_dunder']);
});
