[Tutor] OK, let me revamp my earlier question

[Doug Stanfield]

If you want to iterate over your dials, you need to get them in a data
structure, in the Panel class, that can be iterated over with a for
statement.

 class Panel:
    def __init__(self):
       dial1 = Dial(100)
       dial2 = Dial(75)
       dial3 = Dial(90)
       dial4 = Dial(60)
       dial5 = Dial(65)
       self.dials = [dial1, dial2, dial3, dial4, dial5]

    def updateNormal():
       for dial in self.dials:
           <some code to do what you want, uses the variable 'dial' to
            reference each of the Dial class instances in the list>
