[Tutor] the class struggle

[Lloyd Kvam]

The syntax error probably relates to name.  You show myobject inheriting
from name and then list name as an argument for the __init__ method.

name would have to be a class for the inheritance.  It would probably be
an instance or variable for the argument to init.

I suspect that you really want:
class myObject:

Note that people usually capitalize their classes to help prevent this kind
of confusion.

customer = Customer()	# create a customer instance from Customer class.
