Of course, one could have classes which encapsulate the algorithms, as well as the data, but it also seems natural to me to have algorithms as methods which are part of the data class, so the user operates on the data using methods of that class.

Are these really needing to be methods, or ought they to be
module-level functions? Remember, Python code doesn't have to be
organized into classes the way Java code is.
