There is usually a more Pythonic way of doing things. You need to get adjacent elements from a sequence? Use the pairwise recipe from https://docs.python.org/3/library/itertools.html. -- My fellow Pythonistas, ask not what our language can do for you, ask what you can do for our language. Mark Lawrence
