Convert python 2 constructs to python 3 compatible ones.
In python 3, print is a function, so use write methods (which are always functions) instead.
In python3 keys() returns an iterator, rather than a list. This means you can't change the data structure that is being iterated over. Converting this iterator into a list mimics the python 2 behavior.
