One of the purposes and advantages of Python 3 is having only one class

Thanks for this. I'll keep it in mind!
One thing I really don't understand ... is there a difference between
the old/new forms:
class foo:
class foo():
In cases where I've played with them, they _appear_ to work the same?
I believe they are. Same is true in 3.x except that the result in a
new-style class.
Also, where does one find the magic that says that for a tkinter class
you should use:
class foo(object):
Perhaps nowhere. It may have been an unintended side-effect of the
change in callable check, or intentional but not documented.
Not really sure where "object" comes from.
It is the base class of all (new-style) classes.
>>> object()
<object object at 0x00EB6668>
