Suppose I have def distance2(vector1, vector2): zipped = zip(vector1, vector2) difference2 = [(vector2 - vector1) ** 2 for (vector1, vector2) in zipped] return sum(difference2) where distance2(vector1, vector2) finds the (squared) Euclidian distance between vector1 and vector2. The function will work for iterable elements, but suppose we also want to make it work for non-iterable elements (i.e. distance2(1,3)). Is there a pythonic way to do this? (i.e, automatically turning regular input into a singleton list). Continue reading...
