Overview: Given an n-dimensional matrix, its contents can be checked whether all of its elements evaluate to True or any of its elements evaluate to True. Any can be thought of as a sequence of OR operations on the provided iterables. If any() is used with a dictionary, it checks whether any of the keys evaluate to True, not the values: Whereas, if any() checked the values, the output would have been False.
