Im trying to figure out how to change a string into a name of a Button.
For example if I had the string self._name = 'self._prentice', I would like to make self._prentice = tk.Button(master). I need to do it this way as the string could be any name and I need to create a way of storing this so I can later pack or destroy it. 
I've tried using exec, however I could only get it to work for integers and not buttons.
Use setattr:
setattr(self, '_prentice', tk.Button(master)).
