How embed ipython notebook to wordpress blog as iframe

I am trying to embed iframe hyper linking to the ipython notebook (published using nbviewer) in word press blog.

I am using following code to embed the iframe but it is not working.

   [iframe src="http://nbviewer.ipython.org/github/sharmak/python/blob/master/concepts/Static_Vs_Class_Method.ipynb" width="100%" same_height_as="window" scrolling="yes"]

Any helps ?

Thanks.
