python class design (staticmethod vs method)

Question

What\'s the nicer way for methods that don\'t need any passed information (object instance or class) because for example they just do a simple conversion. @staticmet

Answer 1

My general rule, for all Object Oriented design, is that if a class has no state, consider using static methods. If the class has state, use instance methods - hands down.

Furthermore, if the class indeed has no state, reflect for a few minutes and see if you cannot move the static behavior closer to the data and thereby eliminate those static methods with an Extract Method refactoring.
