Static methods - How to call a method from another method

Question

When I have regular methods for calling another method in a class  I have to do this class test      def   init   self           pass     def dosomething self           print  quot do something quot          self dosomethingelse       def dosomethingelse self           print  quot do something else quot   but when I have static methods I can t write self dosomethingelse    because there is no instance  What do I have to do in Python for calling an static method from another static method of the same class

You can   t call non-static methods from static methods  but by creating an instance inside the static method  It should work like that class test2 object       def   init   self           pass       staticmethod     def dosomething            print  quot do something quot            Creating an instance to be able to           call dosomethingelse    or you           may use any existing instance         a   test2           a dosomethingelse        def dosomethingelse self           print  quot do something else quot   test2 dosomething

OK the main difference between class methods and static methods is    class method has its own identity  that s why they have to be called from within an INSTANCE  on the other hand static method can be shared between multiple instances so that it must be called from within THE CLASS

NOTE - it looks like the question has changed some   The answer to the question of how you call an instance method from a static method is that you can t without passing an instance in as an argument or instantiating that instance inside the static method   What follows is mostly to answer  how do you call a static method from another static method    Bear in mind that there is a difference between static methods and class methods in Python   A static method takes no implicit first argument  while a class method takes the class as the implicit first argument  usually cls by convention    With that in mind  here s how you would do that   If it s a static method   test dosomethingelse     If it s a class method   cls dosomethingelse

If these don t depend on the class or instance  then just make them a function  As this would seem like the obvious solution  Unless of course you think it s going to need to be overwritten  subclassed  etc  If so  then the previous answers are the best bet  Fingers crossed I won t get marked down for merely offering an alternative solution that may or may not fit someone   s needs     As the correct answer will depend on the use case of the code in question
