[split] NameError: name 'start_with_first_selected' is not defined

The same applies you have moved a variable into a class and need to be able to access them from another method, add self. to the front of them to turn it into an attribute.

class TkApp(tk.Tk):
   # these arguments initialize the class and how to form arguments within 
   def __init__(self, *args, **kwargs):
      super().__init__(*args, **kwargs)
      ...
      ...
      ...
      self.group1 = deque((button_1, smman, smauto))
      self.group2 = deque((wsbutton_1, wsbutton_2))
      ...
      ...
      ...

   def start_with_first_selected(self, first_selected=False):
      ...
      ...
      ... 
      self.group1.rotate(1)
      self.group2.rotate(1)
      ...
      ...

OK so that is what you call the different structures methods instead of functions. Not having a book or class learning and really only having google/duckduckgo kind of hurts sometimes. Thank you for that piece of information!

It's in the python docs tutorial

By the way, I use the word attribute for any name following a dot — for example, in the expression z.real, real is an attribute of the object z. Strictly speaking, references to names in modules are attribute references: in the expression modname.funcname, modname is a module object and funcname is an attribute of it. In this case there happens to be a straightforward mapping between the module’s attributes and the global names defined in the module: they share the same namespace!

The other kind of instance attribute reference is a method. A method is a function that “belongs to” an object. (In Python, the term method is not unique to class instances: other object types can have methods as well. For example, list objects have methods called append, insert, remove, sort, and so on. However, in the following discussion, we’ll use the term method exclusively to mean methods of class instance objects, unless explicitly stated otherwise.)

Thanks for that. I will have to reread that tutorial a few times to digest it a little more fully. I had to reference self so many times, I think that this code might be a narcissist...

The fixed code thanks to your pointers:
