There was a problem hiding this comment.
Can we use range in this file instead? I only see one usage of xrange and it is for list size limited by length of pcollections that is going into a cogroupbykey. Assuming that it will not be a large number, I do not think we need to xrange there.

Should we use functools.reduce instead? The reduce is used below in a snippet and we publish those on our website. The example using reduce directly will be broken for python 3 users (they do not see the imports, only the snippet). However if we replace the usage of reduce with functools.reduce it will be a complete snippet.
